Simplify ratios, scale proportions, and solve ratio problems
A ratio calculator helps you work with ratios and proportions. Whether you need to simplify a ratio to its lowest terms, scale a ratio by a factor, or solve proportion problems, our calculator makes these mathematical operations quick and accurate.
Ratios are used in cooking, construction, design, and many other fields. Our tool supports multiple ratio operations to meet your needs.
Simplifying Ratios:
📊 Example:
Simplify the ratio 12:18
GCD(12, 18) = 6
12 ÷ 6 = 2
18 ÷ 6 = 3
Simplified ratio: 2:3
Ratio:
A comparison of two quantities. Example: 3:4 means for every 3 of one thing, there are 4 of another.
Proportion:
An equation stating that two ratios are equal. Example: 3:4 = 6:8
Scaling:
Multiplying both parts of a ratio by the same number. Example: 2:3 scaled by 2 = 4:6
What is the GCD?
The Greatest Common Divisor is the largest number that divides both numbers evenly. It's used to simplify ratios to their lowest terms.
Can ratios have decimals?
Yes, ratios can include decimals. However, they're often simplified to whole numbers for easier understanding.
What's the difference between ratio and fraction?
A ratio compares two quantities (3:4), while a fraction represents a part of a whole (3/4). They're related but used differently.
