Question

foster is centering a photo that is 3 1/2 inches wide on a scrapbook page that is 12 inches wide. How far from each side of the page should he put the picture?

Answer 1

this means that we have to didvide the 12 inches wide side into 3 parts: one of 3.5 inches, and two other, of equal size (the margins).

the margins together will have (12-3.5=8,5) inches, which means that each of them will hace half of this: so we have to divide 8.5 into 2.

this is: :

8.5/2=4.25

so he has to to put it 4.25 inches from each side.
