Answer:

The rate is 1 ÷ 2 yards per hour

Explanation:

The computation of the rate does the amount of yarn changes is given below:

= 3 3 ÷ 4 - 1 1 ÷8

= 15 ÷ 4 - 9 ÷ 8

= 21 ÷ 8 yards

Now divide the above fraction by the number of hours

= 21 ÷ 8 yards ÷ 5 1 ÷ 4

= 21 ÷ 8 × 4 ÷ 21

= 1 ÷ 2 yards per hour

Hence, the rate is 1 ÷ 2 yards per hour

The same would be relevant
