Ratios are a way to compare two or more quantities. A ratio calculator simplifies this process, ensuring accuracy and saving time. This post explains how ratios work, how to use a ratio calculator and common applications.

What Is a Ratio?

A ratio represents the relationship between two or more values. It shows how many times one value contains or is contained within another. Ratios can be written in different formats:

  • Fraction: AB\frac{A}{B}
  • Colon: A:BA:B
  • Words: “A to B”

For example, a ratio of 2:5 means for every 2 units of the first quantity, there are 5 units of the second.

How to Simplify Ratios

To simplify a ratio:

  1. Find the greatest common divisor (GCD) of the numbers.
  2. Divide each number by the GCD.

Example:
Simplify 8:12.

  • GCD of 8 and 12 is 4.
  • Divide both by 4: 84:124=2:3\frac{8}{4} : \frac{12}{4} = 2:3.

The simplified ratio is 2:3.

How a Ratio Calculator Works

A ratio calculator automates the process of simplifying and comparing ratios. Here’s how it helps:

  1. Input Ratios: Enter the numbers in your ratio.
  2. Calculation: The tool finds the GCD and simplifies the ratio.
  3. Result: The calculator displays the simplified ratio in a clear format.
