Fraction of the cherry tarts left
= 1 -
16=
56 The number of cherry and chocolate chip tarts in the end is the same.
Total number of tarts at first
= 6 u + 5 u + 18
= 11 u + 18
11 u + 18 = 117
11 u = 117 - 18
11 u = 99
1 u = 99 ÷ 11 = 9
Number of chocolate chip tarts at first
= 5 u + 18
= 5 x 9 + 18
= 45 + 18
= 63
Answer(s): 63
