Ratio is a mathematical comparison between two or more numbers or quantities. It is used to compare the size, quantity, or amount of one thing to another. Ratios can be expressed as fractions, decimals, or percentages and can be used to compare different measurements or to measure changes over time.

A ratio calculator is a tool used to calculate the ratio between two numbers. It is typically used to compare the relative sizes of two different values. For example, a ratio calculator can be used to calculate the ratio of a person’s height to their weight.

To calculate a ratio, divide one number by another. For example, if you have two numbers, 10 and 20, the ratio would be 10:20 or 1:2. To express this as a fraction, divide 10 by 20 to get 0.5.
