(a)
The total amount that Julian, Oliver and Kimberly had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Julian's shareTotal amount =
515 =
13 (b)
Amount that Kimberly had less than Julian
= 5 u - 2 u
= 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Total amount that Julian, Oliver and Kimberly had
= 15 u
= 15 x 10
= $150
Answer(s): (a)
13; (b) $150
