Question

There are 50 books in the class room library.fifteen of them are non-fiction .what percent of the books are non-fiction?

Answer 1

15 is what % of 50.

Here is a tip ...."of " in math problems means multiply, and " is " means equals.

So write the problem like you read it...
15 is what percent of 50...
15 = y% x 50 or 15 = (y%)(50)
now you need to divide by 50 on both sides to get the y% by itself
15/50 = 50y%/50
.3 = y% (now you need to turn .3 into a percent.
To do that you move the decimal two spaces to the right.
.3 = 30%

check...
30% of 50 = 15
.30 x 50 = 15
15 = 15 (correct)

ANSWER : 30% are non-fiction :)
