Quick Examples

15% of 200

Answer: 30

30 out of 200

Answer: 15%

100 to 120

Answer: 20% increase

How It Works

Percent means “out of 100”. So 15% means 15 out of every 100.

Example: Sarah wants to find 15% of 200. She does 200 x 15 / 100. The answer is 30.

Example: Raj buys a $120 jacket with 25% off. 25% of 120 is 30, so the discount is $30 and he pays $90.

Example: Mia’s hourly pay goes from $25 to $26. The difference is $1. One dollar compared with $25 is 4%, so her pay went up by 4%.
