Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
313 of his money on some beads.
He spends
38 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 =
313 Fraction of his money left after spending on the beads
= 1 -
313=
1013 Fraction of his money spent on the marbles
=
1013 x
38=

125230104 =
1552Amount that Adam spends on the beads = 12 u
(b)
Amount that Adam spends on the marbles = 15 u
(c)
Amount that Adam has in the end
= 52 u - 15 u - 12 u
= 25 u
(d)
Difference in the amount spent on the marbles and beads
= 15 u - 12 u
= 3 u
Answer(s): (a) 12; (b) 15; (c) 25; (d) 3
