Ratio Simplifier
Ratio Simplifier
A ratio like 8:12 carries the same meaning as its simplified form, 2:3, but the simplified version is far easier to read, compare, and reason about. Enter any two whole numbers here, and this calculator divides both by their greatest common divisor to reduce the ratio to its simplest possible form. It works the same way you'd simplify a fraction, and handles large numbers just as easily as small ones — useful for recipes, mixing ratios, aspect ratios, or comparing proportions at a glance.
- Method: both numbers are divided by their greatest common divisor (GCD) to reach the simplest equivalent ratio.
- Example: 8:12 — the GCD of 8 and 12 is 4, so 8÷4 : 12÷4 = 2:3.
- Works for any whole numbers, including large ones — e.g. 144:216 simplifies to 2:3 as well.
What if the ratio is already in simplest form?
The calculator returns the same numbers unchanged — e.g. 2:3 simplifies to 2:3 since its GCD is already 1.
Does this work with decimals?
This tool is designed for whole-number ratios; for decimal ratios, first multiply both numbers by a power of 10 to make them whole numbers.
