(a)
The total amount that Bobby, Justin and Fanny had is repeated. Make the total amount the same. LCM of 3 and 9 is 9.
Fanny's shareTotal amount =
19 (b)
Amount that Fanny had less than Justin
= 5 u - 1 u
= 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Total amount that Bobby, Justin and Fanny had
= 9 u
= 9 x 9
= $81
Answer(s): (a)
19; (b) $81
