How this calculator works
The result depends on the numbers you enter and the assumptions shown below.
A ratio compares two quantities. To simplify, divide both parts by their GCD. Proportions (a:b = c:d) can be solved by cross-multiplication: a×d = b×c.
Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.
Frequently asked questions
How do I simplify a ratio?
Divide both parts of the ratio by their greatest common divisor (GCD). For example, 12:8 → GCD is 4 → simplified to 3:2.
