## What is Ratio?

In mathematics, a ratio indicates how many times one number contains another. The first term of the ratio is known as antecedent while the second term is known as consequent.

For example:

2/5 : 3/4

## How to calculate the ratio?

To find a missing value in ratio, you need to perform cross multiplication.

Example:

Evaluate 3/5 : 3/x

Solution:

Step 1: Cross-multiply both fractions to find the value of x.

3/5 = 3/x

3x = 3*5

3x = 15

x = 15/3

x = 5
