Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
313 of his money on some beads.
He spends
13 of his remaining money on some marbles.
- Amount that Charlie spends on the beads = _____ u
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie 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
13=
1039Make the denominators the same.
313 =
9391039 =
1039Amount that Charlie spends on the beads = 9 u
(b)
Amount that Charlie spends on the marbles = 10 u
(c)
Amount that Charlie has in the end
= 39 u - 10 u - 9 u
= 20 u
(d)
Difference in the amount spent on the marbles and beads
= 10 u - 9 u
= 1 u
Answer(s): (a) 9; (b) 10; (c) 20; (d) 1
