4 u |
Change |
- 3x2 = - 6 u |
- 3 u |
After |
1x2 = 2 u |
1 u |
Comparing Gillian and Parry in the end |
2 u |
1 u |
The number of chocolate bars that Gillian had in the end is repeated. Make the number of chocolate bars that Gillian had in the end the same. LCM of 1 and 2 is 2.
Number of chocolate bars that Gillian had more than Victoria
= 8 u - 4 u
= 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Number of chocolate bars that Victoria had at first
= 4 u
= 4 x 9
= 36
Answer(s): 36
