2) Martha cut three pieces of rope that are 5 1/4 inches each from a rope that is 20 inches
iogann1982 [59]

Answer:

Step-by-step explanation:

Total length of the rope = 20 inches.

Martha cuts 3 pieces of rope that is 5 1/4 inches each.

Find the total length of the 3 pieces of rope:

Total of 3 pieces of rope = 5 1/4 + 5 1/4 + 5 1/4 = 15.75

Since we know the total rope length is 20 inches, if you subtract the total length of the 3 pieces of rope you will get the remaining length of rope.

Remaining length = 20 - 15.75

= 4.25 inches of rope
