Question

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?

Answer 1

Foster needs to place the photograph `4 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 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-:2=4.25`

The distance required to be kept from either side is `4.25` or `4 1/4` inches.
