Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
314 of his money on some beads.
He spends
37 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 =
314 Fraction of his money left after spending on the beads
= 1 -
314=
1114 Fraction of his money spent on the marbles
=
1114 x

3398Make the denominators the same.
314 =
21983398 =
3398Amount that Charlie spends on the beads = 21 u
(b)
Amount that Charlie spends on the marbles = 33 u
(c)
Amount that Charlie has in the end
= 98 u - 33 u - 21 u
= 44 u
(d)
Difference in the amount spent on the marbles and beads
= 33 u - 21 u
= 12 u
Answer(s): (a) 21; (b) 33; (c) 44; (d) 12
