Understanding the Basics of Percentage Maths

A percentage represents a portion of a whole, where the whole is considered to be 100%. The word "percent" literally means "per hundred." Therefore, 25% means 25 out of every 100.

Three Common Percentage Problems

Most percentage problems fall into one of these three categories:

  1. Finding what percent of a number is: For example, what is 15% of 200?
  2. Determining what percentage one number is of another: For example, 30 is what percent of 150?
  3. Calculating percentage increase or decrease: For example, what is the percentage change from 80 to 100?
