How to do ratio equivalents

I think you mean "Equivalent ratios" if that makes sense, but anyways in order to find Equivalent ratios, you have to either multiply or divide both the numerator and denominator of a given ratio by the same number.

For example: Create a table with the numbers of boys and girls

1. Boys: 3

2. Girls: 5

Next set this as a fraction like this

1. 3/5

Then to find equivalent ratios, multiply both numbers by two and you should get

6/10 (because we multiplied the 3/5 by 2)

Next write 6/10 along the chart of boys and girls

(Write them as fraction like this: 3/5 and 6/10)

Ratio of:

Boys: 3, 6

Girls: 5, 10

and there you have found an equivalent ratio.
