How do you do proportions 7th grade?
- a/8. = 10/4.
- a/8 (8 · 4) = 10/4 (8 · 4) Multiply both sides by 8 · 4.
- 4a. = 10 · 8. Simplify.
- 4a. = Simplify.
- a. = Divide both sides by 4.

What is an example of solving proportions?
One basic idea that always works for solving proportions is to first find the unit rate, and then multiply that to get what is asked. For example: if a car travels 110 miles in 3 hours, how far will it travel in four hours? First figure out the unit rate (how far the car goes in 1 hour), then multiply that by 4.

How to Solve Proportions
A proportion is a statement that two ratios are equal. Proportions are usually written with the ratios in fraction form, like this: 1/2 = 2/4. In 7th grade, you'll learn to solve proportions, which means you'll be given a proportion with an unknown variable that you have to identify.
Using Cross-Multiplication
To solve proportions with variables, we use cross-multiplication. It allows us to convert proportions into traditional equations. To demonstrate cross-multiplication, we'll solve this proportion: 1/2 = 2/x. Let's call the fraction on the left side of the equals sign 'Fraction A' and the fraction to the right 'Fraction B.'
Creating Proportions
Many times, you'll use proportions and cross-multiplication to solve word problems, but you won't be given the proportion. Instead, you'll have to set it up yourself. In the following word problem, we demonstrate how to write a proportion and solve it using cross-multiplication.
