(a)
The total amount that Reggie, Jeremy and Gem had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Gem's shareTotal amount =
215 (b)
Amount that Gem had less than Jeremy
= 8 u - 2 u
= 6 u
6 u = 12
1 u = 12 ÷ 6 = 2
Total amount that Reggie, Jeremy and Gem had
= 15 u
= 15 x 2
= $30
Answer(s): (a)
215; (b) $30
