Fraction of the blueberry cupcakes left
= 1 -
16=
56 The number of blueberry and apricot cupcakes in the end is the same.
Total number of cupcakes at first
= 6 u + 5 u + 12
= 11 u + 12
11 u + 12 = 111
11 u = 111 - 12
11 u = 99
1 u = 99 ÷ 11 = 9
Number of apricot cupcakes at first
= 5 u + 12
= 5 x 9 + 12
= 45 + 12
= 57
