Question

Erin is going to sew a jacket and a skirt, She 2 3/4 yards of material for the jacket and 1 1/2 yards of material for the skirt. Altogether how many yards of material does Erin need?

Answer 1

Convert to improper fraction then add together.

2 3/4 yards = 11/4

1 1/2 yards = 3/2

Then convert 3/2 into quarters = 6/4

Then add together 11/4 + 6/4 = 17/4 and convert back to mixed number

17/4 = 4 1/4 yards
