To convert a decimal number to a percentage, multiply by 100/1% so $0.01 = 1$%

#### Explanation:

To convert a decimal number to a percentage, multiply by 100/1%

To convert a percentage to a decimal number, multiply by 1/(100%)

"Percent" means "per hundred"

e.g. 4% means "4 per 100" or "4 out of every hundred"
4% = $\frac{4}{100}$

In the decimal system each position (decimal place) is a factor of 10 from its neighbor.
Moving to the right, each place is $\frac{1}{10}$ of the place to its left:

.... $1000 , 100 , 10 , 1 , \frac{1}{10} , \frac{1}{100} , \frac{1}{1000} ,$... etc

so
$0.01 = \frac{1}{100}$, ..."1 divided by 100" or "1 out of 100" or 1%

$0.11 = \frac{11}{100}$, ...... (0.11 * 100/1% = 11%)

$0.2 = 0.20 = \frac{2}{10} = \frac{20}{100}$ ..... (0.2 * 100/1% = 20%)
