Before |
4x4 = 16 u |
2 u |
Change |
- 3x4 = - 12 u |
- 1 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 Sarah
= 16 u - 2 u
= 14 u
14 u = 28
1 u = 28 ÷ 14 = 2
Number of chocolate bars that Sarah had at first
= 2 u
= 2 x 2
= 4
Answer(s): 4
