(a)
The total amount that Zane, Oliver and Emma had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Zane's shareTotal amount =
515 =
13 (b)
Amount that Emma had less than Zane
= 5 u - 2 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Total amount that Zane, Oliver and Emma had
= 15 u
= 15 x 3
= $45
Answer(s): (a)
13; (b) $45
