Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
25 of his money on some beads.
He spends
34 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 =
25 Fraction of his money left after spending on the beads
= 1 -
25=
35 Fraction of his money spent on the marbles
=

920Make the denominators the same.
25 =
820920 =
920Amount that Charlie spends on the beads = 8 u
(b)
Amount that Charlie spends on the marbles = 9 u
(c)
Amount that Charlie has in the end
= 20 u - 9 u - 8 u
= 3 u
(d)
Difference in the amount spent on the marbles and beads
= 9 u - 8 u
= 1 u
Answer(s): (a) 8; (b) 9; (c) 3; (d) 1
