Question

Micah read 16 pages of his book. if this is 10% of his book how many pages are in the book?

Answer 1

To solve, create a fraction. We know that 10% is equal to 10/100. So, 16 is to what as 10 is to 100, or:
16/x = 10/100
Cross multiply:
10x = 1600
Divide both sides by 10:
x = 160
There are 160 total pages in Micah's book.
