Simplify ratios, solve proportions, and compare values. Enter two or more numbers to find their simplest ratio form instantly.
This tool helps you simplify ratios to their lowest terms and solve proportion problems. A ratio compares two or more quantities, showing their relative sizes. Use it for math homework, recipe scaling, map reading, and more.
Find the greatest common divisor (GCD) of both numbers, then divide each number by the GCD. For example, 12:18 simplifies to 2:3 because GCD(12, 18) = 6.
A proportion states that two ratios are equal, like a:b = c:d. If three values are known, you can solve for the fourth using cross-multiplication.
Currently, this tool works with two-number ratios. For more complex ratios, simplify them in pairs.
