Fraction of the apple wafers left
= 1 -
17=
67 The number of apple and banana wafers in the end is the same.
Total number of wafers at first
= 7 u + 6 u + 17
= 13 u + 17
13 u + 17 = 56
13 u = 56 - 17
13 u = 39
1 u = 39 ÷ 13 = 3
Number of banana wafers at first
= 6 u + 17
= 6 x 3 + 17
= 18 + 17
= 35
Answer(s): 35
