Question

3. An art teacher has a roll of art paper 10 meters long. She needs to cut it into 1-decimeter long pieces for a collage project. How many pieces of paper can she cut from the roll?

Answer 1

Answer: 50

"deci" means tenth, so "decimeter" means "tenth of a meter"

0.10 meter = 1 decimeter

1 meter = 10 decimeters (multiply both sides by 10)

5 meters = 50 decimeters (multiply both sides by 5)

The teacher can get 50 pieces out of the roll of paper

I hope this helps! and have a good day
