Fraction of the apricot shortbreads left
= 1 -
13=
23 The number of apricot and strawberry shortbreads in the end is the same.
Total number of shortbreads at first
= 3 u + 2 u + 20
= 5 u + 20
5 u + 20 = 65
5 u = 65 - 20
5 u = 45
1 u = 45 ÷ 5 = 9
Number of strawberry shortbreads at first
= 2 u + 20
= 2 x 9 + 20
= 18 + 20
= 38
Answer(s): 38
