Ratio Calculator

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: $\frac{A}{B}$
• Colon: $A:B$
• 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: $\frac{8}{4} : \frac{12}{4} = 2:3$.

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.
