Select all that apply.

• A. 1.25 m
• B. 175 cm
• C. 2.75 m
• D. 275 cm

Answer 1

Answer: (C), (D)

The correct options are
C

2.75 m

D

275 cm

To calculate the length of the remaining piece of rope , the units of measurement should be the same.

1 cm = 0.01 m

Hence 25 cm = 0.25 m

Now, length of remaining piece of rope = 3 m - 0.25 m

3.00

- 0.25

_____

2.75 m

We also know 1 m = 100 cm

Hence 2.75 m = 275 cm
