Question 68983: how do you do ratios and percentages?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
a/b is a ratio
per cent means per one hundred. cent is latin for 100
x% means x/100
99% = 99/100
Until you get used to it, just say "per 100" when you see the
per cent sign. You'll know then to divide by 100
