Question

Each DVD storage case is about 1/5 inch thick. What will be the height in simplest form of 12 cases sold together?

Answer 1

Answer:

Height of the 12 cases will be = $2\frac{2}{5}$ inches.

Step-by-step explanation:

Thickness of each DVD storage case = $\frac{1}{5}$ inches

Let number of DVD storage cases sold = x

Therefore, the height of cases sold will be represented by the expression  $\frac{x}{5}$

If the number of cases sold x = 12

So the height of the cases sold will be = $\frac{12}{5}$ inches

                                                                = $2\frac{2}{5}$ inches

Therefore, the answer is $2\frac{2}{5}$ inches.                                                      

Answer 2

2 2/5 inches thick.

1/5 x 12 = 12/5 then make that into a mixed number.
