Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
311 of his money on some marbles.
He spends
34 of his remaining money on some beads.
- Amount that Adam spends on the marbles = _____ u
- Amount that Adam spends on the beads = _____ u
- Amount that Adam has in the end = _____ u
- Difference in the amount spent on the beads and marbles = _____ u
(a)
Fraction of his money spent on the marbles =
311 Fraction of his money left after spending on the marbles
= 1 -
311=
811 Fraction of his money spent on the beads
=

311 =
3112444 =
611Amount that Adam spends on the marbles = 3 u
(b)
Amount that Adam spends on the beads = 6 u
(c)
Amount that Adam has in the end
= 11 u - 6 u - 3 u
= 2 u
(d)
Difference in the amount spent on the beads and marbles
= 6 u - 3 u
= 3 u
Answer(s): (a) 3; (b) 6; (c) 2; (d) 3
