Question

A roll of ribbon was 12 meters long. Diego cut 9 pieces of ribbon that were 0.4 meter each to tie some presents. He then used the remaining ribbon to make some wreaths. Each wreath required 0.6 meter. How many meters of ribbon were available for making wreaths?

Answer 1

5.4

Explanation:

We have 12 meters total,Diego: 9 pieces × 0.4 meters= 3.6 meters

So Diego used up 3.6 meters of ribbon

Part A: 9-3.6=5.4 meters left

Answer 2

Answer: 8.4 meters

Explanation:

From the question, we are informed that a roll of ribbon was 12 meters long and that Diego cut 9 pieces of ribbon that were 0.4 meter each to tie some presents. The length of ribbon used by Diego for the present would be:

= 9 × 0.4meter

= 3.6 meter.

Therefore, the meters of ribbon that were available for making wreaths would be:

= 12 meters - 3.6 meters

= 8.4 meters
