Question

An art student uses a roll of wallpaper to decorate two gift boxes. The student will use 1 1 4 yards of paper for one box and 7 8 yard of paper for the other box. The paper must be cut into pieces that are 1 8 yard long. How many pieces will the student cut to use for the gift boxes?

Answer 1

Answer:

17 pieces

Step-by-step explanation:

The student use $1\dfrac{1}{4}$ yards of paper for one box and $\dfrac{7}{8}$ yard of paper for the other box.

Total no of rolls required is the sum of  $1\dfrac{1}{4}$ yards and $\dfrac{7}{8}$ yard. So,

$S=1\dfrac{1}{4}+\dfrac{7}{8}\\\\=\dfrac{5}{4}+\dfrac{7}{8}\\\\=\dfrac{17}{8}$

Let there are x no of pieces will the student cut to use for the gift boxes. It can be calculated as :

$x=\dfrac{\dfrac{17}{8}}{\dfrac{1}{8}}\\\\=17$

Hence, the student will cut 17 pieces to use the gift boxes.
