Ratio vs. Percentage: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on November 8, 2023
A ratio compares two quantities, while a percentage represents a part per hundred of a whole.

Key Differences

A ratio is a relationship between two numbers showing how many times the first number contains the second. It is expressed using the colon symbol (:) or as a fraction. Ratios are used to compare different types of quantities without requiring them to have the same units. For example, if there are 2 apples for every 3 oranges, we have an apple-to-orange ratio of 2:3.

A percentage is a way of expressing a number as a fraction of 100, denoted using the percent symbol (%). It is used to describe how large one quantity is in relation to another where the second quantity is always 100. For instance, if 50 out of 100 apples are red, then 50% of the apples are red.

Ratios provide a direct comparison between two quantities, which can be scaled up or down proportionally. Percentages, however, relate specifically to a proportional part of a whole based on a scale of 100, which makes it a dimensionless number. This means that percentages are often used to compare parts of a whole without concern for the size of the whole.

Ratios can be converted into percentages by finding the equivalent fraction that has 100 as the denominator. Conversely, a percentage can be expressed as a ratio by converting the percentage to a fraction of the form x/100, and then simplifying it if possible.

Both ratios and percentages are essential tools in mathematics and are used for different purposes. Ratios are useful for showing the relative sizes of two quantities, while percentages are excellent for showing parts of a whole in an easily understood format because they are always on the same scale: out of 100.
