Gleen neds to cut pieaces of ribbion that are each 1 meter long .if he has 3 pieaces of ribbion that are each 1 dekameter long, how many 1 meter pieaces can he cut?

1 decameter is 10 meters long so 30 ribbons of 1 meter

Well, since a dekameter is a metric unit of measurement that is equivalent to 10 meters, 3 pieces of ribbon that are 1 dekameter long is 3 deka meters. (3x10=30). So this is equivalent to 30 meters, and he needs each piece to be 1 meter long, which means there are 30 pieces of ribbon he can cut. Hope this helped :)!
