The number of strawberry shortbreads Liam baked was

7x3 =
21 u |
The number of other shortbreads remains unchanged. Make the number of other shortbreads the same. LCM of 3 and 1 is 3.
Number of more strawberry shortbreads baked
= 18 u - 5 u
= 13 u
13 u = 156
1 u = 156 ÷ 13 = 12
Number of shortbreads that Liam baked at first
= 8 u
= 8 x 12
= 96
Answer(s): 96
