Fraction of the apple cupcakes left
= 1 -
15=
45 The number of apple and strawberry cupcakes in the end is the same.
Total number of cupcakes at first
= 5 u + 4 u + 19
= 9 u + 19
9 u + 19 = 64
9 u = 64 - 19
9 u = 45
1 u = 45 ÷ 9 = 5
Number of strawberry cupcakes at first
= 4 u + 19
= 4 x 5 + 19
= 20 + 19
= 39
Answer(s): 39
