The total amount that Cody, Ahmad and Fiona had is repeated. Make the total amount the same. LCM of 3 and 15 is 15.
Fiona's shareTotal amount =
215 (b)
Amount that Fiona had less than Ahmad
= 8 u - 2 u
= 6 u
6 u = 66
1 u = 66 ÷ 6 = 11
Total amount that Cody, Ahmad and Fiona had
= 15 u
= 15 x 11
= $165
Answer(s): (a)
215; (b) $165
