- 5x1 =

- 9 |
After

1x1 =
1 u |
8 u - 9 |
The number of cupcakes at first is repeated. Make the number of cupcakes at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 8 u - 9
= 9 u - 9
9 u - 9 = 72
9 u = 72 + 9
9 u = 81
1 u = 81 ÷ 9 = 9
Number of more cupcakes than muffins that Ahmad sold
= 5 u - 9
= 5 x 9 - 9
= 45 - 9
= 36
Answer(s): 36
