Fraction of the blueberry macarons left
= 1 -
15=
45 The number of blueberry and cherry macarons in the end is the same.
Total number of macarons at first
= 5 u + 4 u + 20
= 9 u + 20
9 u + 20 = 92
9 u = 92 - 20
9 u = 72
1 u = 72 ÷ 9 = 8
Number of cherry macarons at first
= 4 u + 20
= 4 x 8 + 20
= 32 + 20
= 52
Answer(s): 52
