# Find the missing piece

A paper length is 1½ m. One section is 5/8 m. What length belongs to the remaining section? Show the whole and both parts in a sketch, then check by adding.

**A way to check:** 12/8 − 5/8 = 7/8 m. The check is 5/8 + 7/8 = 12/8 = 1½ m. Keep the same whole and unit in every step.
