1x1 =
1 u |
8 u - 19 |
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 - 19
= 9 u - 19
9 u - 19 = 44
9 u = 44 + 19
9 u = 63
1 u = 63 ÷ 9 = 7
Number of more cupcakes than biscuits that Fabian sold
= 5 u - 19
= 5 x 7 - 19
= 35 - 19
= 16
Answer(s): 16
