How To Teach Proportions
To introduce proportions to students, give them tables of equivalent rates to fill in, such as the one below. This will help them learn proportional reasoning.
| Miles |
Of course the students should notice that it is easy to fill in the table if you first figure out the unit rate then find the other amounts.

Write Percent Equations As Proportions
Previously, we solved percent equations by applying the properties of equality we have used to solve equations throughout this text. Some people prefer to solve percent equations by using the proportion method. The proportion method for solving percent problems involves a percent proportion. A percent proportion is an equation where a percent is equal to an equivalent ratio.
For example, 3 5 shows a percent equal to an equivalent ratio, we call it a percent proportion. Using the vocabulary we used earlier:
The amount is to the base as the percent is to 100
If we restate the problem in the words of a proportion, it may be easier to set up the proportion:
We could also say:
First we will practice translating into a percent proportion. Later, weâll solve the proportion.

Ratios And Proportions And How To Solve Them
Let’s talk about ratios and proportions. When we talk about the speed of a car or an airplane we measure it in miles per hour. This is called a rate and is a type of ratio. A ratio is a way to compare two quantities by using division as in miles per hour where we compare miles and hours.
A ratio can be written in three different ways and all are read as “the ratio of x to y”
$$x\: to\: y$$
$$x:y$$
$$\frac$$
A proportion on the other hand is an equation that says that two ratios are equivalent. For instance if one package of cookie mix results in 20 cookies than that would be the same as to say that two packages will result in 40 cookies.
$$\frac=\frac$$
A proportion is read as “x is to y as z is to w”
$$\frac=\frac \: where\: y,w\neq 0$$
If one number in a proportion is unknown you can find that number by solving the proportion.
Example
You know that to make 20 pancakes you have to use 2 eggs. How many eggs are needed to make 100 pancakes?
| 100 |
$$\frac=\frac\: \: or\: \: \frac=\frac$$
If we write the unknown number in the nominator then we can solve this as any other equation
$$\frac=\frac$$
Multiply both sides with 100
$$ }\, \frac= }\, \frac$$
$$x=\frac$$
$$x=10$$
If the unknown number is in the denominator we can use another method that involves the cross product. The cross product is the product of the numerator of one of the ratios and the denominator of the second ratio. The cross products of a proportion is always equal
$$\frac }} }}=\frac }} }}$$
$$xw=yz$$

The Next Step: Proportion Problems And Thinking
After studying tables of equivalent rates, the students are ready to tackle word problems. Choose simple ones at first, and let them think! They might very well come up with an answer on their own by making a table or by figuring out the unit rate. So… you don’t actually need to write an actual proportion to solve a proportion word problem.
However, I don’t want to put down equations or cross-multiplying students studying algebra and pre-algebra courses still need to learn to solve proportions with cross-multiplying. It’s just that learning to use common sense is even more important.
