The number of apricot shortbreads Liam baked was
27 of the total number of shortbreads. After baking another 104 apricot shortbreads, the number of apricot shortbreads became
34 of the total number of shortbreads. How many shortbreads did she bake at first?

Apricot shortbreads |
Other shortbreads |
Total shortbreads |
| Before |
2 u |
5 u |
7 u |
| Change |
+ 104 |
|

| After |
3x5 =
15 u |
1x5 =
5 u |
4x5 =
20 u |
The number of other shortbreads remains unchanged. Make the number of other shortbreads the same. LCM of 5 and 1 is 5.
Number of more apricot shortbreads baked
= 15 u - 2 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Number of shortbreads that Liam baked at first
= 7 u
= 7 x 8
= 56
Answer(s): 56
