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