Before |
7x4 = 28 u |
4 u |
Change |
- 6x4 = - 24 u |
- 3 u |
After |
1x4 = 4 u |
1 u |
Comparing Victoria and Parry in the end |
4 u |
1 u |
The number of chocolate bars that Victoria had in the end is repeated. Make the number of chocolate bars that Victoria had in the end the same. LCM of 1 and 4 is 4.
Number of chocolate bars that Victoria had more than Pamela
= 28 u - 4 u
= 24 u
24 u = 288
1 u = 288 ÷ 24 = 12
Number of chocolate bars that Pamela had at first
= 4 u
= 4 x 12
= 48
Answer(s): 48
