Fraction of the banana wafers left
= 1 -
14=
34 The number of banana and cherry wafers in the end is the same.
Total number of wafers at first
= 4 u + 3 u + 11
= 7 u + 11
7 u + 11 = 109
7 u = 109 - 11
7 u = 98
1 u = 98 ÷ 7 = 14
Number of cherry wafers at first
= 3 u + 11
= 3 x 14 + 11
= 42 + 11
= 53
Answer(s): 53
