Look for repeated identity. (1) Jimmy is repeated, the units should the same. It happens that here Jimmy with Paul or with Mary, he has 2 units. No need to adjust. Check Mary(2). Mary is 2 units compared with Raymond, 5 units when compared with Jimmy. Smallest common multiple of 2 and 5 is 10, so make units of Mary 10 at the end. After,adjust other affected units belonging to other children.
