Before |
8 u |
4x3 = 12 u |
3 u + 6 |
Change |
- 5 u |
- 3x3 = - 9 u |
- 6 |
After |
3 u |
1x3 = 3 u |
3 u |
(a)
The number of cupcakes that Paul and Brandon each had in the end is the same. Make the number of cupcakes that Paul and Brandon each had in the end the same. LCM of 3 and 1 is 3.
Number of cupcakes that Paul had less than Brandon at first
= 12 u - 8 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
Number of cupcakes that Paul had at first
= 8 u
= 8 x 8
= 64
(b)
Total number of cupcakes that the 3 of them bought
= 8 u + 12 u + 3 u + 6
= 23 u + 6
= 23 x 8 + 6
= 184 + 6
= 190
Answer(s): (a) 64; (b) 190
