Three friends each have some ribbon. Carl has 54 inches of ribbon,Tino has 13.5 feet of ribbon, and Baxter has 3.5 yards of ribb

deff fn [24]

Answer:

342 inches, or 28.5 feet, or 9.5 yards

Step-by-step explanation:

It is perhaps easiest to start with all the dimensions in inches.

13.5 ft = (13.5 ft)(12 in/ft) = 162 in

3.5 yd = (3.5 yd)(36 in/yd) = 126 in

Then the total of the lengths of ribbon is ...

54 in + 162 in + 126 in = 342 in

Converting to feet, we get ...

(342 in)/(12 in/ft) = 28.5 ft

And converting to yards, we get ...

(342 in)/(36 in/yd) = 9.5 yd

The total length of ribbon is 342 inches, or 28.5 feet, or 9.5 yards.
