What percent of 80 is 16?
20.
How did they get that answer??
of means times. Is means equals.
DecimalPercent x 80= 16
divide both sides by 80
decimal percent = 16/80= .2
percent=decimalpercent x 100
There is a formula for that -- but I never learned it. I like to set up a proportion for this kind of problem.
Let x equal the number out of 100 (the percent).
x / 100 = 16 / 80
x = 20
