| Before |
6x2 =
12 u |
4 u |
| Change |
- 5x2 =
- 10 u |
- 3 u |
| After |
1x2 =
2 u |
1 u |
Comparing Jen
and Parry in the end |
2 u |
1 u |
The number of jelly beans that Jen had in the end is repeated. Make the number of jelly beans that Jen had in the end the same. LCM of 1 and 2 is 2.
Number of jelly beans that Tiffany had less than Jen
= 12 u - 4 u
= 8 u
8 u = 16
1 u = 16 ÷ 8 = 2
Number of jelly beans that Jen had at first
= 12 u
= 12 x 2
= 24
Answer(s): 24
