Answer 2

Answer:

2 4/7

Step-by-step 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
