- 3x3 =
- 9 u |
- 6 |
After

1x3 =
3 u |
8 u - 6 |
The number of tarts at first is repeated. Make the number of tarts at first the same. LCM of 3 and 4 is 12.
Total number of pastries left
= 3 u + 8 u - 6
= 11 u - 6
11 u - 6 = 38
11 u = 38 + 6
11 u = 44
1 u = 44 ÷ 11 = 4
Number of more tarts than croissants that Liam sold
= 9 u - 6
= 9 x 4 - 6
= 36 - 6
= 30
Answer(s): 30
