(a)
The total amount that Lee, Luke and Rachel had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Lee's shareTotal amount =
515 =
13 (b)
Amount that Rachel had less than Lee
= 5 u - 3 u
= 2 u
2 u = 6
1 u = 6 ÷ 2 = 3
Total amount that Lee, Luke and Rachel had
= 15 u
= 15 x 3
= $45
Answer(s): (a)
13; (b) $45
