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

Foster needs to place the photograph $4 \frac{1}{4}$ inches from each side of the page.

#### Explanation:

To determine how to place the photograph in the centre of the page, we need to find the difference in the widths and then divide that by $2$ which will be the distance from either side of the page.

Since $3 \frac{1}{2}$ is the same as $3.5$, we will subtract using decimals.

The difference is $12 - 3.5 = 8.5$

Knowing that the scrapbook page is $8.5$ inches wider than the photograph, we divide that width by $2$ to get the distance from either side of the page.

The distance is $8.5 \div 2 = 4.25$

The distance required to be kept from either side is $4.25$ or $4 \frac{1}{4}$ inches.
