# Ratio of 3 Numbers Calculator

With this Omni's ratio of 3 numbers calculator you'll never again struggle with finding the ratio of 3 numbers ** A : B : C**! This tool can perform various math operations related to ratios of three numbers, for instance

**simplify**them or determine

**equivalent ratios**. In what follows, we briefly recall

**how to calculate the ratio of 3 numbers**and go together through some examples.

## How do I calculate the ratio of 3 numbers?

Recall that ratios represent the quantitative relationship between two or more numbers, i.e., **how many times one number is bigger/smaller than other numbers**. In particular, the ratio `A : B : C`

describes the ratio between the numbers `A`

, `B`

and `C`

.

For example, if to bake a cake you need 100 g of butter, 200 g of sugar and 400 g of flour, then your ingredients are in ratio `100 : 200 : 400`

. You need two times more flour than sugar and two times more sugar than butter. And, obviously, four times more flour than butter. That is, our ratio can be equivalently written as `1 : 2 : 4`

. Here, we've simplified the ratio by dividing all three numbers by `100`

. On the other hand, to determine the amount of ingredients for two cakes, it's best to write our ratio as `200 : 400 : 800`

. That is, we've multiplied each element o the initial ratio by `2`

.

## How do I simplify a ratio of three numbers?

To simplify a ratio of three numbers `A : B : C`

:

- Write down the factors of
`A`

, of`B`

, and of`C`

. - Determine the
**greatest common factor (GCF)**of`A`

,`B`

, and`C`

. - Divide the three numbers in the ratio by the number from Step 2.

## FAQ

### How do I divide $50 in ratio 2 : 3 : 5?

To find out how to divide a given amount of money based on a ratio of three numbers:

- Add the numbers appearing in the ratio:
`2 + 3 + 5 = 10`

. There's**ten parts in total**. - Divide the total amount of money by the result of Step 1:
`$50 / 10 = $5`

.**One part is five dollars**. - The first person gets two parts, so
`$10`

. The next person gets three parts, so`$15`

. The last person gets five parts, that is`$25`
