Before |
6x3 = 18 u |
4 u |
Change |
- 5x3 = - 15 u |
- 3 u |
After |
1x3 = 3 u |
1 u |
Comparing Vanessa and Parry in the end |
3 u |
1 u |
The number of jelly beans that Vanessa had in the end is repeated. Make the number of jelly beans that Vanessa had in the end the same. LCM of 1 and 3 is 3.
Number of jelly beans that Vanessa had more than Zara
= 18 u - 4 u
= 14 u
14 u = 154
1 u = 154 ÷ 14 = 11
Number of jelly beans that Zara had at first
= 4 u
= 4 x 11
= 44
Answer(s): 44
