Numbers can be whole numbers, decimals, or fractions
The calculator handles ratios of any size and complexity
How the Calculation Works
Ratio calculations involve comparing quantities using division and simplification. A ratio a:b means a divided by b, or a/b. Equivalent ratios multiply or divide by the same number (2:3 = 4:6 = 6:9). To simplify ratios, find the greatest common divisor (GCD) and divide all parts by it. For example, 4:6 simplifies to 2:3 by dividing by 2. Ratios connect to fractions (2:3 = 2/3) and percentages, forming the foundation of proportional reasoning used throughout mathematics and science.
Example Scenarios
Recipe scaling: A cookie recipe calling for 2:3:4 (flour:sugar:butter) for 12 cookies scales to 4:6:8 for 24 cookies by multiplying by 2.
Mixing solutions: A 1:3 chemical solution needs 1 part chemical to 3 parts water; for 4 liters total, use 1 liter chemical and 3 liters water.
Map scaling: A map with 1:100,000 ratio means 1 cm on map equals 100,000 cm (1 km) in reality.
Financial ratios: A 2:1 debt-to-equity ratio means company has $2 in debt for every $1 in equity.

Frequently Asked Questions
What's the difference between a ratio and a fraction?
A ratio compares two or more quantities (like 2:3), while a fraction represents a part of a whole (like 2/3). Ratios show relationships between different things, while fractions show parts of the same thing. For example, a 2:3 ratio might compare apples to oranges, while 2/3 represents two-thirds of a single apple. Ratios can be converted to fractions (2:3 = 2/3), but they represent different mathematical concepts.
How do I simplify ratios?
To simplify a ratio, find the greatest common divisor (GCD) of all numbers and divide each part by it. For 4:6, the GCD is 2, so 4÷2:6÷2 = 2:3. For 6:9:12, the GCD is 3, so 6÷3:9÷3:12÷3 = 2:3:4. Always divide by the largest number that divides evenly into all parts. Simplified ratios are easier to work with and compare.
How do I find equivalent ratios?
Multiply or divide all parts of the ratio by the same number. For 2:3, multiply by 2 to get 4:6, multiply by 3 to get 6:9, etc. Divide by common factors to simplify. Equivalent ratios represent the same relationship but with different numbers. They're useful for scaling recipes, mixing solutions, or comparing different-sized versions of the same proportion.
How do ratios work in real life?
Ratios appear everywhere: cooking (2:1 flour to sugar), mixing (1:4 chemical to water), maps (1:25,000 scale), finance (debt-to-equity ratios), photography (aspect ratios), and construction (mixing concrete). Understanding ratios helps scale recipes, dilute solutions, interpret maps, analyze finances, and solve proportional problems. Ratios make complex relationships simple and predictable.
What's a proportion and how does it relate to ratios?
A proportion is an equation showing two ratios are equal (like 2:3 = 4:6). Proportions solve problems by finding missing values when ratios are equal. For example, if 2 apples cost $1, how much do 6 apples cost? Set up proportion: 2/1 = 6/x, solve for x = $3. Proportions extend ratios by allowing calculations of unknown quantities while maintaining the same relationship.
