Question

Emma uses a 250 meter roll of crepe paper to make streamers. How many dekameters of creme paper does emma use?

Answer 1

1 meter = 0.1 decameters

0.1 * 250 = 25

So she used 25 decameters of creme paper.

Answer 2

We have to convert meters to dekameters.

1 dekameter= 10 meters 

250/10= 25

Emma uses 25 dekameters of creme paper.
