About Ratio Calculator
The Ratio Calculator simplifies complex ratios into their most basic, irreducible form. Ratios are used universally in baking, chemistry, aspect ratios for screens, and financial leverage metrics.
How Ratio Calculator Works
- Step 1: Input A and B: Enter the two sides of your ratio. For example, if your screen resolution is 1920x1080, enter 1920 in A and 1080 in B.
- Step 2: Calculate: The tool runs a Euclidean algorithm to find the greatest number that divides both A and B without a remainder, and outputs the simplified ratio (e.g., 16:9).
Frequently Asked Questions
What does it mean to simplify a ratio?
Simplifying a ratio means dividing both sides by their highest common factor until they cannot be divided any further while remaining whole numbers. 10:5 simplifies to 2:1.
Can a ratio have decimals?
Technically yes, but standard mathematical convention dictates that ratios should be expressed as whole integers. If you enter decimals, you should multiply them by a power of 10 to make them whole numbers before simplifying.
