About this tool
Simplify a ratio A : B and scale it to a new size.
Both parts are divided by their greatest common divisor. Scaling keeps the ratio: B′ = A′ × B ÷ A.
Formula: A : B = A/g : B/g, g = gcd(A, B)
Example: A = 1,920, B = 1,080, New value for A (optional) = 1,280 → Simplified A = 16, Simplified B = 9.
Simplifying needs whole numbers; decimals are scaled but not reduced.
