Answer:
32 such pieces can be cut from the total length of gum.
Step-by-step explanation:
The total length of the gum = 6 ft
Now, 1 ft = 12 inches
So, 6 ft = 6 x 12 inches = 72 inches
Now, length of each piece =
inches =
inches
So, to find the total number of pieces of desired length
Divide the total length of gum by the length of each piece.
or, n = 
Hence, 32 such pieces can be cut from the total length of gum.
10 out of 50 equals 0.2
20% is the answer.
