Fraction of the cherry shortbreads left
= 1 -
17=
67 The number of cherry and cheese shortbreads in the end is the same.
Total number of shortbreads at first
= 7 u + 6 u + 17
= 13 u + 17
13 u + 17 = 69
13 u = 69 - 17
13 u = 52
1 u = 52 ÷ 13 = 4
Number of cheese shortbreads at first
= 6 u + 17
= 6 x 4 + 17
= 24 + 17
= 41
Answer(s): 41
