Homework Help: math

Posted by Mack on Tuesday, June 26, 2007 at 7:42pm.

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
