Question

A worker at a construction store has been asked to cut a 48-foot piece of rope into pieces that are each 4.5 feet long.

Part a: How many 4.5 pieces of rope can be cut from the 48-foot piece of rope?

Part b: How many feet of rope would be left over? ​

Answer 1

a) 10 pieces

b) 3 feet

Explanation:

a) The number of useful pieces of rope will be the integer part of the result from ...

48/4.5 = 10 2/3

That is, 10 pieces of rope 4.5 feet long can be cut from a rope 48 feet long.

__

b) Those pieces total (4.5 ft)×10 = 45 ft, so the amount left over is ...

48 ft -45 ft = 3 ft

3 feet of rope will be left over.

Answer 2

Explanation:

The total length of the piece of rope that the worker at the construction store was asked to cut into pieces that are each 4.5 feet long is 48-foot.

Therefore, the number of 4.5 feet pieces of rope that can be cut from the 48-foot piece of rope would be

48/4.5 = 10.7

Since the length must be 4.5 feet, then only 10 pieces can be cut

Part b

The length of rope that would be leftover is 48 - 45 = 3 feet
