Question

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

If he has 2 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?

Glenn needs
pieces.

Answer 1

Answer: 20

Step-by-step explanation: 1 decameter has 10 meters so if he has 2 decameter long ribbons than it would be 20 meters.

Answer 2

He can cut 20 1-meter pieces since 1 decametre is equal to 10 meters. So you divide 20 meters by 1 which will give you 20 pieces.

1 decametre = 10 meters
2 decametres = 10 meters x 2
= 20 meters
