Question

Jada was using square stickers that were 3/4in long to decorate the spine of a photo album. The spine is 10 and 1/2in long. If she laid the stickers side by side without gaps or overlaps, how many stickers did she use to cover the length of the spine?

Answer 1

13

Explanation:

Given:

1. Square stickers that were 3/4 in long
2. The spine is 10 and 1/2 in long

If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine:

`(The length of the spine)/(the length of the sticker)`

10 :
`(3)/(4)` ≈13

She needs 13 stickers cover the length of the spine

Answer 2

Explanation:

Given:

Length of square stickers, l = 3/4 in

Dimensions of the photo album spine:

Length, Lp = 10 × 1/2 in

Number of stickers × square stickers = length of photo album spine

Assume, width of photo album = 3/4 in

Number of stickers = 21/2 ÷ 3/4

= 14 stickers.
