2x3 =
6 u |
1x3 =
3 u |
3x3 =
9 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 banana cupcakes baked
= 6 u - 4 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of cupcakes that Oscar baked at first
= 7 u
= 7 x 7
= 49
Answer(s): 49
