Question

You want to make a scarf and matching hat. The pattern calls for 1 7/8 yards of fabric for the scarf and 2 1/2 yards of fabric for the hat. How much fabric do you need all?

Answer 1

4 3/8 yards.

Explanation:

1 7/8 + 2 1/2

= 15/8 + 5/2

Make the denominator 8 in both cases ( The LCM = 8):

= 15/8 + 20/8

= 35/8

= 4 3/8.
