# Question: How To Ratio Math?

## How do you calculate a ratio?

To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out \$20 shared in the ratio of 1:3. Step 1 is to work out the total number of parts in the ratio. 1 + 3 = 4, so the ratio 1:3 contains 4 parts in total.

## How do I calculate a ratio between two numbers?

Evaluate Equivalent Ratios:

1. Add the ratio terms to get the whole. Use this as the denominator. 1: 2 => 1 + 2 = 3.
2. Convert the ratio into fractions. Each ratio term becomes a numerator in a fraction. 1: 2 => 1/3, 2 /3.
3. Therefore, in the part-to-part ratio 1: 2, 1 is 1/3 of the whole and 2 is 2 /3 of the whole.

## What is the ratio of 3 to 5?

3: 5 =?: 40. ( 3 out of 5 is how many out of 40?) ” 5 goes into 40 eight times. Eight times 3 is 24.”
