The number of cards that Kylie had at first and in the end remains unchanged. Make the number of cards that Kylie had the same. LCM of 6 and 2 is 6.
Number of cards that Kylie had more than Roshel at first
= 6 u - 4 u
= 2 u
2 u = 158
1 u = 158 ÷ 2 = 79
Number of cards that Roshel had at first
= 4 u
= 4 x 79
= 316
Answer(s): 316
