kendra knits hats. She starts with 3 3/4 yd of yarn. After knitting for 5 1/4 h their is 1 1/8 yd of yarn left. At what rate does the amount of yarn changes. Show your work

The rate is  1 ÷ 2 yards per hour

Step-by-step 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
