How do you use ratios and proportions?
Proportions: Our example: 4/x = 7/9First, find which fraction is missing a number/is replaced with a variable. In this case, it is the first one: 4/x. Next, cross multiply. You multiply the number shown in the variable fraction by the opposite number in the other fractions. So you would multiply 4x9, because one is a numerator and the other is a denominator. Once you get that number, divide it by the other number not used, which would be 7. 36 divided by 7 is 5.142857>. That means x=5.142857. Ratios: Ratios are any equations that compare numbers, like fractions or proportions. They can be written in proportion form: 4/5=7/8, or fraction form: 9/20.
