Question

Ebony is building a shelf to hold the two boxes shown. What is the least width she should make the shelf?

Answer 1

There exists the same question from other source that shows the two boxes.

Box 1 has a length of 4/5 feet
Box 2 has a length of 3/4 feet

Because Ebony is trying to find the total amount of space needed to hold the boxes, use addition.

Here, is the solution:
= 4 / 5 + 3 / 4
= (16 + 15) / 20
= 31 / 20

So, Ebony can make a shelf at least 31/20 feet wide or 1 11/20 feet.
