What is Meant by Proportion?

In Mathematics, a proportion is defined as a statement that the two ratios should be equal. The symbols to represent the proportion are “::” or “=”. If p/q and r/s are two equal ratios, then we can write them in proportion as given below:

p/q = r/s


p : q :: r : s

For example, 1/4 = 4/16. This can also be written in form 1:4 = 4:16. When two ratios are of equal value, then the values are in equal proportion. 

Also, read: Ratio and Proportion

From the above-given example, ¼ = 4/16 are in proportion, because, when the right-hand side is simplified, we get the ratio of the left-hand side. Then the proportion becomes 1:4 = 1:4.
