(a)
The total amount that Julian, Jack and Kylie had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Kylie's shareTotal amount =
215 (b)
Amount that Kylie had less than Jack
= 8 u - 2 u
= 6 u
6 u = 42
1 u = 42 ÷ 6 = 7
Total amount that Julian, Jack and Kylie had
= 15 u
= 15 x 7
= $105
Answer(s): (a)
215; (b) $105
