What is the Ratio Calculator?
A ratio compares two quantities, showing how many times one contains the other. Simplifying a ratio divides both sides by their greatest common divisor so it's expressed in the smallest whole numbers.
How to Calculate
Find the greatest common divisor (GCD) of both numbers, then divide each by it. For example 8 : 12 has GCD 4, giving 2 : 3.
Formula
Simplified = (A ÷ GCD) : (B ÷ GCD)
