Question

elena sews a ribbon across the bottom of a scarf that is one yard long .she has sewed 3/8 yard of ribbon so far.how much more ribbon does she need to sew to finish the whole scarf?

Answer 1

`Total \: length = 1 \: yard \\ Finished \: length = (3)/(8) \: yard \\ \\ so \: remaining \: length \\ = total \: length - finished \: length \\ = 1 \: yard - (3)/(8) \: yard \\ = (8)/(8) \: yard - (3)/(8) \: yard \\ = (5)/(8) yard`

This is the answer.

Hope it helps!!
