Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
411 of his money on some marbles.
He spends
23 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 =
411 Fraction of his money left after spending on the marbles
= 1 -
411=
711 Fraction of his money spent on the beads
=
711 x
23=
1433Make the denominators the same.
411 =
12331433 =
1433Amount that Adam spends on the marbles = 12 u
(b)
Amount that Adam spends on the beads = 14 u
(c)
Amount that Adam has in the end
= 33 u - 14 u - 12 u
= 7 u
(d)
Difference in the amount spent on the beads and marbles
= 14 u - 12 u
= 2 u
Answer(s): (a) 12; (b) 14; (c) 7; (d) 2
