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

1225Make the denominators the same.
15 =
5251225 =
1225Amount that Adam spends on the beads = 5 u
(b)
Amount that Adam spends on the marbles = 12 u
(c)
Amount that Adam has in the end
= 25 u - 12 u - 5 u
= 8 u
(d)
Difference in the amount spent on the marbles and beads
= 12 u - 5 u
= 7 u
Answer(s): (a) 5; (b) 12; (c) 8; (d) 7
