<h3>Answer:  3/4</h3>

=========================================================

Explanation:

We'll use this formula

a & b/c = (a*c + b)/c

to convert from a mixed number to an improper fraction.

John's mixed number converts to

a & b/c = (a*c + b)/c

6 & 3/4 = (6*4 + 3)/4

6 & 3/4 = 27/4

Do the same for Kerry's string

a & b/c = (a*c + b)/c

7 & 1/2 = (7*2 + 1)/2

7 & 1/2 = 15/2

We'll subtract those results to find the difference between them.

15/2 - 27/4 = 30/4 - 27/4 = (30-27)/4 = 3/4 is the final answer

Kerry's string is 3/4 of an inch longer compared to John's string.

Answer:

¾

Step-by-step explanation:

Length of Kerry string = 7(½) = 15/2

Length of John string = 6(¾) = 27/4

15/2 - 27/4

30 - 27/4

3/4
