# What is a ratio?

A ratio is a direct comparison of one number against another. A ratio calculator looks to define the relationship that compares between those two numbers

## Using the Ratio Calculator

Use the ratio calculator to solve ratio/proportion problems and to test equivalent fractions. A ratio of 1/2 can be entered into the ratio calculator as 1:2, 2/10 would be 2:10.

The ratio calculator will then produce a table of equivalent ratios. The ratio calculator will also process decimal numbers

## Where are Ratio Calculations Used?

# How to Calculate Ratios

When calculating equivalent ratios you must multiply or divide both numbers in the ratio. This keeps both numbers in direct relation to each other. So, a ratio of 2/3 has an equivalent ratio of 4/6: in this ratio calculation we simply multiplied both 2 and 3 by 2.
