Comparing Winnie and Parry at first |
108 more |
|
Before |
4x4 = 16 u |
4 u |
Change |
- 3x4 = - 12 u |
- 3 u |
After |
1x4 = 4 u |
1 u |
Comparing Winnie and Parry in the end |
4 u |
1 u |
The number of chocolate bars that Winnie had in the end is repeated. Make the number of chocolate bars that Winnie had in the end the same. LCM of 1 and 4 is 4.
Number of chocolate bars that Winnie had more than Ivory
= 16 u - 4 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Number of chocolate bars that Ivory had at first
= 4 u
= 4 x 9
= 36
Answer(s): 36
