In my previous post on Percentage, we saw how the % symbol helps us determine how to convert Percentages to decimals. For example, 20% converts to 0.2 because 20% is really 20 divided by 100. As a fraction, it would be 20/100.
If converting from Percentage to decimal or fraction is to divide by 100, all it is to convert from fractions or decimals would then be to multiply by 100. It is really that simple... :)
