A rug layer can put down 7/8 square yard of carpeting in 1/20 hour. What is the unit rate in square yards per hour?

17/5 sq yd per hour

Step-by-step explanation:

7/8 sq yd per 1/20 hr = x sq yd per 1 hr

We can set up equivalent proportions and cross-multiply.

7/8 × 1 = 1/20 × x

7/8 = 1/20 x

Multiply both sides by 20.

x = 7/8 × 20

  = 140/8

  = 35/2

x = 17.5 sq yd
