Question

A waitress earned a 18% tip.What decimal is equivalent to 18%

Answer 1

0.18

Explanation:

Percentages and decimals are closely related. As a matter of fact, we don't need to use any actual math to solve this question because there is a shortcut.

Answer by Dividing

One way to solve the question is by dividing. Percentages are numbers that represent a portion of 100. So, to find the decimal form we can divide the percentage by 100.

• 18/100 = 0.18

Shortcut

While dividing by 100 can work, there is an easier way to find the decimal form. Dividing by 100 will always be equivalent to moving the decimal point 2 digits to the left.

• This means that 18.0 becomes 0.18 when using this shortcut.
