lutik1710 [3]

Answer:

A total of 387 centimeters of ribbon are used.

Step-by-step explanation:

We already know that two out of three pieces of ribbon are 1.25 meters.

The third piece of ribbon is 120 millimeters (mm) longer.

1 millimeters = 0.001 meters

120 x 0.001 = 0.12

That means that the third piece of ribbon is 0.12 meters longer than the first two. The length of the third ribbon is 1.25 m + 0.12 m = 1.37 m

In order to find the total number of meters of ribbon used, we need to do addition.

1.25 m + 1.25 m + 1.37 m = 3.87 m

But, the question is asking us the number of centimeters of ribbon that are used.

1 m = 100 cm

3.87 x 100 = 387 cm

Therefore, a total of 387 centimeters of ribbon are used.

Hope this helps! Have a blessed day! :)
