# Equivalent Ratios

The equivalent ratio is like the equivalent fractions so to find the equivalent ratio we need to write it in the form of a fraction. To find the equivalent ratio we need to multiply or divide the numerator and denominator with the same number.

Example

Find the two equivalent ratios of 5: 20.

Solution

First multiply it by 2.

So the two equivalent ratios are 10:40 and 1: 4.

To compare that the two ratios are equivalent or not we need to convert them in the form of like a fraction. Like fractions are the fractions with the same denominator.

Example

Check, whether the ratios 2: 3 and 3: 4 are equivalent are not?

Solution

To check, first, we need to make their denominator same.

Hence the ratio 2:3 is not equivalent to 3:4.
