Question

A fabric store has `80 3/8` yd of a particular fabric. About how many pairs of curtains could be made from this fabric if each pair requires `4 1/8` yd of fabric?

Answer 1

19 pairs

Explanation:

We can convert the mixed numbers to imperfect fractions, then divide.

`80 3/8 -: 4 1/8`

`643/8 -: 33/8`

When we divide fractions, we can invert the right fraction and multiply:

`643/cancel8 xx cancel8/33=643/33=19.bar48~~19` pairs
