Ebony is building a shelf to hold the two boxes showed what is the least with she should make the shelf the boxes are 4/5 feet t
Alona [7]

Answer:

  4/5 ft

Step-by-step explanation:

Assuming both boxes need to fit completely on the shelf, Ebony should make it as wide as the largest of the boxes.

In decimal, 4/5 = 0.80 and 3/4 = 0.75, so 4/5 > 3/4.

The shelf should be 4/5 ft wide.
