Apile of newspapers in mr. mcraths class was 17 3/4 inches high. each consecutive week, for the next five weeks, the height of the pile of newspapers increased by 8 7/12 inches. what was the height, in inches, after 3 weeks

Hi.

The first step to understanding this is to know what operations are involved. In this case, multiplication and addition are gonna be used.

Let's find out how much we're going to add to the original height of the newspaper pile.

8 7/12 · 3  = 25 3/4

The product of the amount each week and the number of weeks ^

Add the product to the original pile.
17 3/4 + 25 3/4 = 43 1/2

Mr. Crath's newspaper pile was 43 1/2 inches tall after 3 weeks.

Hope this helps!
