He spends
12 of his remaining money on some marbles.
- Amount that Charlie spends on the beads = _____ u
- Amount that Charlie spends on the marbles = _____ u

(a)
Fraction of his money spent on the beads =
14 Fraction of his money left after spending on the beads
= 1 -
14=
34 Fraction of his money spent on the marbles

38Amount that Charlie spends on the beads = 2 u
(b)
Amount that Charlie spends on the marbles = 3 u
(c)
Amount that Charlie has in the end
= 8 u - 3 u - 2 u
= 3 u
(d)
Difference in the amount spent on the marbles and beads
= 3 u - 2 u
= 1 u
Answer(s): (a) 2; (b) 3; (c) 3; (d) 1
