Ratio Calculator: Simplify, Compare, and Solve Ratio Problems Instantly

Ratios are fundamental mathematical concepts used everywhere - from cooking recipes to financial analysis. Our Ratio Calculator provides a powerful yet simple solution for all your ratio-related calculations, helping you solve problems quickly and accurately.

Understanding Ratios

A ratio compares two or more quantities, showing their relative sizes. Ratios can be expressed in three ways:

• Using "to" (3 to 4)
• With a colon (3:4)
• As a fraction (3/4)

Common Ratio Problems and Solutions

Problem 1: Simplifying Ratios

Question: Simplify the ratio 48:72
Solution: Divide both numbers by 24 to get 2:3

Problem 2: Finding Missing Values

Question: If 3:7 = 15:x, find x
Solution: Cross-multiply: 3x = 105 → x = 35

Problem 3: Combining Ratios

Question: Mix liquids in ratios 2:3 and 1:4, find the combined ratio
Solution: Find common denominator (20) → 8:12 and 5:20 → combined 13:32

Tips for Working with Ratios

• Always reduce ratios to simplest form for easier comparison
• When adding ratios, find a common denominator first
• For scaling up, multiply both terms by the same number
• Remember that ratios compare quantities, not necessarily actual amounts
• Use our calculator to verify manual calculations

Frequently Asked Questions

1. What's the difference between a ratio and a fraction?

While similar, ratios compare parts to parts, while fractions compare parts to a whole.

2. How do I convert a ratio to a percentage?

Divide the first number by the second and multiply by 100 (3:4 = 3/4 = 75%).

3. Can ratios have more than two numbers?

Yes! You can have ratios like 2:3:5 for comparing three quantities.

4. How do I handle ratios with different units?

Convert to the same unit first (e.g., 1ft:6in becomes 12in:6in = 2:1).
