How Do You Simplify A Problem

Reducing Fractions to Lowest Terms – MathHelp.com

Here are the basic steps to follow to simplify an algebraic expression:

• remove parentheses by multiplying factors.
• use exponent rules to remove parentheses in terms with exponents.
• combine like terms by adding coefficients.
• combine the constants.
• Reduce Algebraic Fractions To Its Lowest Term

If the numerator and denominator of an algebraic fractionhave no common factor other than 1, it is said to be in the lowest form.

The reduced form of an algebraic fraction means there is no common factor between the numerator and denominator of the given algebraic fractions. That means, if there is any common factor present in the numerator and denominator then by keeping the value of the algebraic fraction unchanged, the common factor is freed by mathematical method and the algebraic fraction will be reduced to its lowest form.

When we reduce an algebraic fraction to its lowest term we need to remember if the;numerator and denominator of the fractions are multiplied or divided by the same quantity, then the value of the fraction remains unchanged.

To reduce algebraic fractions to its lowest term, we need to follow the following steps:

Step I:;take the factorization of polynomial in the numerator and denominator.

Step II:;then cancel out the common factors in the numerator and denominator.

Step III:;reduce the given algebraic fraction to the lowest term.

Note: The H.C.F. of numeratorand denominator is 1.

For example:

1. In the numerator ma and the denominator mb of \, isthe common factor, so the algebraic fraction \ is not in its lowest terms.Now, divide both the numerator and denominator by the common factor m then weget \ = \ there is no common factor, so \ is the algebraicfraction which is in reduced form.

How Does Reduce_sum Work In Tensorflow

I am learning tensorflow, I picked up the following code from the tensorflow website. According to my understanding, axis=0 is for rows and axis=1 is for columns.

How are they getting output mentioned in comments? I have mentioned output according to my thinking against ##.

`import tensorflow as tfx = tf.constanttf.reduce_sum  #  ## tf.reduce_sum  #  ##tf.reduce_sum  # 6 ## Didn't understand at all.`

x has a shape of :

`1 1 11 1 1`

The input is a 2-D tensor:

`1 1 11 1 1`

The 0 axis in tensorflow is the rows, 1 axis is the columns. The sum along the 0 axis will produce a 1-D tensor of length 3, each element is a per-column sum. The result is thus . Likewise for the rows.

The sum along both axes is, in this case, the sum of all values in the tensor, which is 6.

Comparison to numpy:

`a = np.arraynp.sum       #  np.sum       # np.sum)  # 6`

As you can see, the output is the same.

Think it like that, the axis indicates the dimension which will be eliminated. So for the first case axis 0, so if you go through this dimension they will all collapse into 1. Thus it will be as following:

`result =  + ] =  `

So you removed dimension 0.

Now, for the second case, you will collapse axis 1 , so:

`result =  +  + ] = `

And the last case is you keep collapsing in order indicated in the brackets. In other words, first you eliminate the rows and then the columns:

`result1 = result_final = 2 + 2 + 2 = 6 `

Hope this helps!

Topics Related to Reduce Fractions

• Example 1: Reduce the following fractions by the GCF method. a) 16/64, b) 18/81

Solution: We will use the GCF method to reduce fractions.

a) The greatest common factor of 16 and 64 is 16. Dividing the numerator and the denominator by 16, we get the fraction reduced to 1/4. 16/64 = / = 1/4. Therefore, the reduced form of 16/64 is 1/4

b) The greatest common factor of 18 and 81 is 9. Dividing the numerator and the denominator by 9, we get the fraction reduced to 2/9. 18/81 = / = 2/9. Therefore, the reduced form of 18/81 is 2/9

• Example 3: Reduce the fraction / 2

Solution: In order to reduce fractions with variables in the question, we will factorize the expressions given in the numerator and the denominator.

The numerator x2 + 5x + 6 can be factorized as x2 + 5x + 6 = . Now, / 2 = / 2. Cancelling out the common factors we get, / . Therefore, the reduced form of the fraction / 2 is /

• How Do You Reduce Fractions With Exponents

To reduce fractions with exponents, apply the exponent rules to the numerator and the denominator. For example, n = an/bn, where ‘a’ and ‘b’ are the numerator and denominator respectively and ‘n’ is the exponent of the fraction. After evaluating the fraction using the exponent rules, reduce the fraction to its simplest form. For example, let us reduce 3. This can be reduced and written as 3 and then using the exponent rules, this can be written as 13/23 = 1/8.

Why Is The Gcf Used In Reducing Fractions

While reducing fractions, we use the GCF to divide the numerator and the denominator because the GCF is the largest number that divides the numerator and the denominator, so, it becomes easier to reduce the fractions. The other common factors of the numerator and the denominator are smaller and thus, they take more time and steps to reduce the fraction. For example, let us reduce the fraction: 12/18. The GCF of 12 and 18 is 6. So, we can use 6 to divide the numerator and the denominator in just one step. / = 2/3

The Meaning Of Root Of Unity

Learn How To Reduce A Fraction In 7 Minutes

The root of unity refers to the state in which for any integer;n,;the;nth;root of a number k;is a number that, when multiplied by itself n;times, yields the number;k. A root of unity in, most simply put, any number which when multiplied by itself any number of times always equals 1. Therefore, an;nth root of unity is any number;k that satisfies the following equation:

k^n; = 1 , where;n is a positive integer.

Roots of unity are also sometimes called de Moivre numbers, after the French mathematician Abraham de Moivre. Roots of unity are traditionally used in branches of mathematics like number theory.

When considering real numbers, the only two that fit this definition of roots of unity are the numbers one and negative one . But the concept of the root of unity does not generally appear within such a simple context. Instead, the root of unity becomes a topic for mathematical discussion when dealing with complex numbers, which are those numbers that can be expressed in the form a;+;bi, where;a;and;b;are real;numbers and i;is the square root of negative one or an imaginary number. In fact, the number i is itself also a root of unity.

How To Convert An Improper Fraction To A Mixed Fraction

To convert an improper fraction to a mixed number, we divide the numerator by the denominator. Then, we write the quotient as the whole number, the remainder as the new numerator and the denominator remains the same. For example, to convert 26/7 to a mixed fraction, we will divide 26 by 7. This will give 3 as the quotient and 5 as the remainder. So, the mixed fraction will be \

How Are Fractions Reduced To Their Lowest Terms

To reduce a fraction into its simplest form, divide the numerator and denominator by the highest common factor. For example, let us reduce 16/64. The highest common factor of 16 and 64 is 16. So, we will divide the numerator and the denominator by 16. / = 1/4. Therefore, the reduced form of 16/64 is 1/4.

How To Reduce Fractions

Reducing fractions means simplifying a fraction, wherein we divide the numerator and denominator by a common divisor until the common factor becomes 1. In other words, a fraction cannot be divided anymore by the same whole number other than 1. For example, consider the fraction 8/24. Here is the step by step process to reduce the fraction.

• Step 1: Write the factors of the numerator and the denominator. The factors of 8 are 1, 2, 4, and 8, and the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24
• Step 2: Determine the common factors of the numerator and the denominator. The common factors of 8 and 24 are 1, 2, 4, and 8
• Step 3: Divide the numerator and denominator by the common factors until they have no common factor except 1. The fraction thus obtained is in the reduced form.

Let’s start dividing by 2: / = 4/12. We will continue to divide by 2 until we can’t go any further. So, we have / = 2/6 = / = 1/3. Therefore, the reduced form of 8/24 is 1/3

Let us take another example.

Example: Reduce the fraction, 10/20. We will find out a common factor of the numerator and the denominator. Repeat the process until there are no more common factors. 5 is a common factor of both 10 and 20. On dividing the numerator and denominator by 5, we get, 10/20 = / = 2/4. The fraction reduces to 2/4 in the first step. Now, 2 is a common factor of 2 and 4. Reducing the fraction further, / = 1/2. Therefore, the reduced form of 10/20 is 1/2.

What Does Domain Reduction Mean

Can any one tell me what does domain reduction mean? can you show me an example for that to make it clear to me?

Thanks very much.

• 1\$\begingroup\$Can you clarify the context? What does this have to do with calculus? A search on domain reduction turns up “finite group of symmetries of a system of linear equations” …\$\endgroup\$Jun 26 ’13 at 4:08
• 2\$\begingroup\$I believe what you are thinking of, is to restrict the domain of a function, in order to have a well-defined inverse function.\$\endgroup\$;Calvin LinJun 26 ’13 at 4:09
• \$\begingroup\$Indeed this is surely the idea of restricting a function to a smaller domain. Do note that occasionally mathematicians will intertwine subject-specific jargon with more ubiquitous terms understood by their colloquial meaning, or otherwise rearrange technical terms as if they were just any old words. In particular, “reduction” here is understood in the everyday sense of “something goes from bigger to smaller, more to less”; the phrase “domain reduction” is not itself standard in how it is being used here.\$\endgroup\$Jun 26 ’13 at 4:15
• \$\begingroup\$It means you boil the domain until you get the desired consistency.\$\endgroup\$

Reducing Rational Expressions In X

Now that weve discussed some fundamental ideas and techniques, lets apply what weve learned to rational expressions that are functions of an independent variable . Lets start with a simple example.

Example \

Reduce the rational expression \ to lowest terms. For what values of x is your result valid?

Solution

In the numerator, factor out a 2, as in 2x 6 = 2.

The denominator is a quadratic trinomial with ac = = 12. The integer pair 3 and 4 has product 12 and sum 7, so the denominator factors as shown.

Now that both numerator and denominator are factored, we can cancel common factors.

Thus, we have shown that \

In equation , we are stating that the expression on the left is identical to the expression on the right for all values of x.

Actually, there are two notable exceptions, the first of which is x = 3. If we substitute x = 3 into the left-hand side of equation , we get

We cannot divide by zero, so the left-hand side of equation is undefined if x = 3. Therefore, the result in equation is not valid if x = 3.

Similarly, if we insert x = 4 in the left-hand side of equation ,

Again, division by zero is undefined. The left-hand side of equation is undefined if x = 4, so the result in equation is not valid if x = 4. Note that the right-hand side of equation is also undefined at x = 4.

On the other hand, if we substitute x = 5 into the right-hand side of equation ,

Remember that we placed the left- and right-hand sides of equation in Y1 and Y2, respectively.

What Does It Really Mean To Simplify A Fraction

Reducing Fractions

Teaching fractions to students can sometimes become complicated especially when the teacher relies on how he or she was taught fractions. I can remember when I was in school my teacher would call simplifying a fraction reducing. When I realized that I loved math so much I decided to stop teaching ;5th grade math and science and enter the world of ;middle school math. By the time I began teaching middle school the words reducing fractions had been stricken from the list of math vocabulary words and replaced with simplifying fractions. At first I was confused as to why reducing fractions had been changed to simplifying fractions. So, I decided to dig a little deeper and look up the word simplify. The definition of simplify means to make less complex or complicated; make plainer or easier. I began to wonder how does this definition apply to teaching fractions.

I realized when working with fractions the denominator is always the focus. This also holds true when applying the word simplify to a fraction. In the picture the fraction 3/9 has 9 parts and is not in simplest form because there are 9 individual parts that are is apart of the fraction. In the world of fractions a fraction that has several parts is more complicated or complex.
