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% = #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 #1/10# of the place to its left:

.... #1000, 100, 10, 1, 1/10, 1/100, 1/1000, #... etc

so
#0.01 = 1/100#, ..."1 divided by 100" or "1 out of 100" or 1%

#0.11 =11/100#, ...... (#0.11 * 100/1% = 11#%)

#0.2 = 0.20 = 2/10 = 20/100# ..... (#0.2 * 100/1% = 20#%)
