The types of percentage.

In Mathematics, there are two main types of percentage and these include the following:

  1. Percentage decrease
  2. Percentage increase

Mathematically, percentage increase can be calculated by using this formula:

Percentage increase = [Final value - Initial value]/Initial value × 100

Substituting the given parameters into the formula, we have;

Percentage increase = [100 - 80]/80 × 100

Percentage increase = [20]/80 × 100

Percentage increase = 1/4 × 100

Percentage increase = 25%.
