Question
PERCENT TO DECIMAL, DECIMAL TO PERCENT
Percent is an abbreviation of the Latin words per centum, meaning “by the hundred." So percent means dvie
by 100." A percent can be written as a decimal. To change a percent to a decimal, first write the percent as a
fraction with a denominator of 100, then divide by 100.
EXAMPLE
Change 31% to a decimal.
EXAMPLE
Change 17.3% to a decimal.
SOLUTION
31% = 31/100 = 0.31
SOLUTION
17.3% =73/100 = 0.173
When dividing by 100, you can just move the decimal point two places to the left. When you write a
percent as a decimal, you are moving the decimal point two places to the left and dropping the percent
sign (%). If necessary, use zero as a placeholder.
EXAMPLE
SOLUTION
А.
31%
31% = 31, = 0.31
Drop % sign.
-Move decimal 2 places.

В.
7% = 07;

= 0.07
-Insert a zero as a placeholder.
To write a decimal as a percent, move the decimal point two places to the right and add a percent sign (%).
EXAMPLE
SOLUTION
А.
0.31
0.31 = 0,31 = 31% + Add % sign.
-Move decimal 2 places.
В.
0.07
0.07 =
0.07 = 7%
