Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
15 of his money on some marbles.
He spends
12 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 =
15 Fraction of his money left after spending on the marbles
= 1 -
15=
45 Fraction of his money spent on the beads
=

15410 =
25Amount that Adam spends on the marbles = 1 u
(b)
Amount that Adam spends on the beads = 2 u
(c)
Amount that Adam has in the end
= 5 u - 2 u - 1 u
= 2 u
(d)
Difference in the amount spent on the beads and marbles
= 2 u - 1 u
= 1 u
Answer(s): (a) 1; (b) 2; (c) 2; (d) 1
