Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
29 of his money on some marbles.
He spends
25 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 =
29 Fraction of his money left after spending on the marbles
= 1 -
29=
79 Fraction of his money spent on the beads
=
79 x
25=
1445Make the denominators the same.
29 =
10451445 =
1445Amount that Adam spends on the marbles = 10 u
(b)
Amount that Adam spends on the beads = 14 u
(c)
Amount that Adam has in the end
= 45 u - 14 u - 10 u
= 21 u
(d)
Difference in the amount spent on the beads and marbles
= 14 u - 10 u
= 4 u
Answer(s): (a) 10; (b) 14; (c) 21; (d) 4
