(a)
The total amount that Fred, Pierre and Min had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Min's shareTotal amount =
215 (b)
Amount that Min had less than Pierre
= 8 u - 2 u
= 6 u
6 u = 72
1 u = 72 ÷ 6 = 12
Total amount that Fred, Pierre and Min had
= 15 u
= 15 x 12
= $180
Answer(s): (a)
215; (b) $180
