(a)
The total amount that Oliver, Henry and Fiona had is repeated. Make the total amount the same. LCM of 3 and 12 is 12.
Fiona's shareTotal amount =
112 (b)
Amount that Fiona had less than Henry
= 7 u - 1 u
= 6 u
6 u = 12
1 u = 12 ÷ 6 = 2
Total amount that Oliver, Henry and Fiona had
= 12 u
= 12 x 2
= $24
Answer(s): (a)
112; (b) $24
