Ratio Calculator - Simplify, Solve for Missing Value, and Scale ์†Œ๊ฐœ

Free ratio calculator with three modes. Simplify: reduce A:B to lowest terms using GCD. Solve: find the missing value in a proportion A:B = C:D. Scale: multiply both sides of a ratio by any factor. Great for cooking scale-ups, model-making, mixing ratios, and math homework.

How is a ratio simplified?

Divide both sides by their greatest common divisor (GCD). 12:18 โ†’ 2:3 (GCD = 6).

How do you solve A:B = C:D?

Cross-multiply. If C is unknown: C = A ร— D รท B. If D is unknown: D = B ร— C รท A.
