9 x 7 |
1 x 7 |

7 x 1 |

63 u |
7 u |
4 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 1 and 7.
LCM of 1 and 7 = 7
Bryan : Adam : Charlie
63 : 7 : 4
Total amount that Bryan, Adam and Charlie have
= 63 u + 7 u + 4 u
= 74 u
74 u = 592
1 u = 592 ÷ 74 = 8
Amount that Charlie has less than Bryan
= 63 u - 4 u
= 59 u
= 59 x 8
= $472
Answer(s): $472
