| After |
3x3 =
9 u |
1x3 =
3 u |
4x3 =
12 u |
The number of other cupcakes remains unchanged. Make the number of other cupcakes the same. LCM of 3 and 1 is 3.
Number of more blueberry cupcakes baked
= 9 u - 5 u
= 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Number of cupcakes that Vaidev baked at first
= 8 u
= 8 x 9
= 72
Answer(s): 72
