The total amount that Liam and Ethan have is repeated. Make the total amount of Liam and Ethan the same. LCM of 4 and 3 is 12.
The total amount that Ben, Liam and Ethan have is repeated. Make the total amount of Ben, Liam and Ethan the same. LCM of 20 and 4 is 20.
Total amount that Ben, Liam, Ethan and Michael shared = 35 u
35 u = 245

Amount that Michael had if Ethan gave him all his money
= 15 u + 9 u
= 24 u
Amount that Michael had more than Liam
= 24 u - 3 u
= 21 u
= 21 x 7
= $147
Answer(s): $147
