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

To find the percent of 80 that is 16, you can set up a proportion. Let x represent the unknown percent.

The equation can be set up as follows:

x / 100 = 16 / 80

To solve for x, you can cross multiply:

80x = 16 * 100

Then divide both sides of the equation by 80:

x = (16 * 100) / 80

Simplifying further,

x = 1600 / 80

x = 20

Therefore, 20% of 80 is 16.
