- 3x1 =
- 3 u |
- 8 |
After

1x1 =
1 u |
6 u - 8 |
The number of tarts at first is repeated. Make the number of tarts at first the same. LCM of 2 and 4 is 4.
Total number of pastries left
= 1 u + 6 u - 8
= 7 u - 8
7 u - 8 = 55
7 u = 55 + 8
7 u = 63
1 u = 63 ÷ 7 = 9
Number of more tarts than macarons that Paul sold
= 3 u - 8
= 3 x 9 - 8
= 27 - 8
= 19
Answer(s): 19
