Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
16 of his money on some beads.
He spends
23 of his remaining money on some marbles.
- Amount that Charlie spends on the beads = _____ u
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie has in the end = _____ u
- Difference in the amount spent on the marbles and beads = _____ u
(a)
Fraction of his money spent on the beads =
16 Fraction of his money left after spending on the beads
= 1 -
16=
56 Fraction of his money spent on the marbles

16 =
3181018 =
1018Amount that Charlie spends on the beads = 3 u
(b)
Amount that Charlie spends on the marbles = 5 u
(c)
Amount that Charlie has in the end
= 18 u - 5 u - 3 u
= 10 u
(d)
Difference in the amount spent on the marbles and beads
= 5 u - 3 u
= 2 u
Answer(s): (a) 3; (b) 5; (c) 10; (d) 2
