Question

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains.

If he has 9 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

Answer 1

9514 1404 393

Answer:

90

Explanation:

1 dekameter is 10 meters, so each of Glenn's 9 pieces of ribbon can be cut to make 10 1-meter pieces.

9 × 10 m = 90 m . . . . length of available ribbon

(90 m)/(1 m/piece) = 90 pieces

Glenn can cut 90 1-meter pieces from the ribbon he has.
