9.5 Percentages

Percent (or percentage) means "out of 100." We use the percent symbol (%) as a way to write a fraction with a common denominator of 100.

Method

  1. Write the given percentage as a fraction with denominator 100.
  2. Multiply this fraction with the given number.
Example:
50% of 40
(50/100)*40 = 20
Answer: 20

Example:
25% of 48
(25/100)*48 = 12
Answer: 12

Example:
222% of 77
(222/100)*77 = 176
