Explanation:

let n = number to add to 5 3/7

change 5 3/7 to improper fraction: 38

7

change 8 to become 56

7

create equation:

38 + n = 56

7 7

n = 56 - 38

7 7

n = 18 or 2 4/7

7

check: 5 3 + 2 4 = 8

7 7

5 + 2 = 7 and 3/7 + 4/7 = 1

7 + 1 = 8

Answer 2

2 4/7

3/7+4/7= 7/7 or 1 whole

So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8
