- 5x1 =
- 5 u |
- 17 |
After

1x1 =
1 u |
4 u - 17 |
The number of croissants at first is repeated. Make the number of croissants at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 4 u - 17
= 5 u - 17
5 u - 17 = 3
5 u = 3 + 17
5 u = 20
1 u = 20 ÷ 5 = 4
Number of more croissants than puffs that Will sold
= 5 u - 17
= 5 x 4 - 17
= 20 - 17
= 3
Answer(s): 3
