25 of her cards, Nicole had thrice as many cards as Jean. How many cards did Jean have at first?

- 2 u |
| After |
|
3 u |
Comparing Nicole
and Jean in the end |
3x3 =
9 u |
1x3 =
3 u |
The number of cards that Nicole had at first and in the end remains unchanged. Make the number of cards that Nicole had the same. LCM of 9 and 3 is 9.
Number of cards that Nicole had more than Jean at first
= 9 u - 5 u
= 4 u
4 u = 96
1 u = 96 ÷ 4 = 24
Number of cards that Jean had at first
= 5 u
= 5 x 24
= 120
Answer(s): 120
