Question

Sam had 1 1-2 m of rope. He cut off 5-8 m and used it for the project. How much does Sam have left​

Answer 1

1 1/2 m and 5/8 meter need to have the same denominator in order to subtract.

1 1/2 is equivalent to 12/8
Now 5/8 and 12/8 have the same denominator so you can subtract.
12/8-5/8= 7/8
7/8 m is left
