c) 10 pieces
d) 2.5 pieces
Show a diagram to illustrate your solution.

Answer 1

Noah can cut 10 pieces of 1/2 meter rope from the 5 meters he has. If he doubles the length of the rope to 10 meters, he can cut 20 pieces.

Step-by-step explanation:

Noah has five meters of rope and wants to cut it into pieces that are 1/2 meter long. To find out how many pieces of rope he can cut, we divide the total length of the rope by the length of each piece:

5 meters ÷ 1/2 meter = 10 pieces

Therefore, Noah can cut 10 pieces of 1/2 meter rope from the 5 meters he has. When considering the doubled length of rope, which would be 10 meters, he could then cut:

10 meters ÷ 1/2 meter = 20 pieces

So, with twice the length of rope, Noah can cut 20 pieces that are each 1/2 meter long.

Referring to the proportions mentioned, such as 1/20=1/5.5, these are not directly related to the current problem and seem to be part of another exercise. Hence, we focus only on the division calculation for this question.
