Simplify ratios, solve proportions (find missing value), and scale ratios up or down.
Enter 3 values, leave one blank (?) to find it. A:B = C:D
A Ratio Calculator simplifies ratios to their lowest terms and can also find equivalent ratios or solve for a missing value in a proportion.
The tool divides both numbers in a ratio by their Greatest Common Factor to reduce it to the simplest equivalent form while keeping the same proportional relationship.
Enter the two numbers forming your ratio. Click Calculate. The tool shows the simplified ratio along with the decimal and percentage equivalent.
Example 1: The ratio 8 to 12 simplifies to 2 to 3.
Example 2: The ratio 25 to 100 simplifies to 1 to 4.
Example 3: The ratio 15 to 45 simplifies to 1 to 3.
Scaling recipes up or down while keeping proportions accurate. Comparing prices or quantities for the best value. Solving map scale and distance problems. Mixing solutions or paints in correct proportions.
What does it mean to simplify a ratio. It means expressing it in the smallest whole numbers that keep the same proportion.
Can a ratio have more than two numbers. Yes, ratios can compare three or more quantities, like 2 to 3 to 5.
Is a ratio the same as a fraction. Ratios and fractions are related but used differently, a ratio compares two quantities directly.
How do I find an equivalent ratio. Multiply or divide both numbers in the ratio by the same value.
Can ratios include decimals. Yes, though they are often converted to whole numbers for clarity.
