Jada was using square stickers with a side length of 3/434 inch to decorate the spine of a photo album. The spine is 10 1/21012
Yuki888 [10]

Answer: The number of stickers she used to cover the length of the spine = 14.

Step-by-step explanation:

Given: The length of spine = 10\dfrac12 inches  = \dfrac{21}{2} inches

Length of each sticker = \dfrac34 inch

If she laid the stickers side by side without gaps or overlaps, the number of stickers she use to cover the length of the spine = \text{(Length of spine)}\div (\text{Length of each sticker})

=\dfrac{21}{2}\div\dfrac{3}{4}\\\\=\dfrac{21}{2}\times\dfrac{4}{3}\\\\=\dfrac{7\times2}{1}=14

The number of stickers she used to cover the length of the spine = 14.
