Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
213 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 =
213 Fraction of his money left after spending on the beads
= 1 -
213=
1113 Fraction of his money spent on the marbles
=
1113 x
23=
2239Make the denominators the same.
213 =
6392239 =
2239Amount that Charlie spends on the beads = 6 u
(b)
Amount that Charlie spends on the marbles = 22 u
(c)
Amount that Charlie has in the end
= 39 u - 22 u - 6 u
= 11 u
(d)
Difference in the amount spent on the marbles and beads
= 22 u - 6 u
= 16 u
Answer(s): (a) 6; (b) 22; (c) 11; (d) 16
