Question

Joey has 30 pages to read for history class tonight. He decided that he

would take a break when he finished reading 70% of the pages assigned.
How many pages must he read before he takes a break?

Answer 1

The answer is 21 pages

Explanation:

the equation would look like this

30*0.70= x

you have to make sure the seven would be behind the decimal point because you are gonna get a number less than 30, which the answer ends up being

30(.70)= 21

21 pages
