Calculate with ratios: simplify to lowest terms, scale to specific values, solve proportions with missing values, and compare ratios. Essential for cooking, construction, finance, and everyday math.
A ratio compares two quantities, showing how much of one thing there is relative to another. Written as a:b or a/b, ratios can be simplified like fractions. For example, 4:6 simplifies to 2:3. Ratios are used for mixing recipes, scaling drawings, and calculating proportions.
Ratio Formula
a : b = a/bScale recipes up or down while maintaining proportions.
Mix concrete, mortar, or paint in correct proportions.
Calculate financial ratios like debt-to-income.
Scale maps and technical drawings accurately.
Find the greatest common divisor (GCD) of both numbers and divide both by it. For example, 12:18 has GCD of 6, so 12/6 : 18/6 = 2:3.
