Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
415 of his money on some marbles.
He spends
23 of his remaining money on some beads.
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie spends on the beads = _____ u
- Amount that Charlie 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 =
415 Fraction of his money left after spending on the marbles
= 1 -
415=
1115 Fraction of his money spent on the beads
=
1115 x
23=
2245Make the denominators the same.
415 =
12452245 =
2245Amount that Charlie spends on the marbles = 12 u
(b)
Amount that Charlie spends on the beads = 22 u
(c)
Amount that Charlie has in the end
= 45 u - 22 u - 12 u
= 11 u
(d)
Difference in the amount spent on the beads and marbles
= 22 u - 12 u
= 10 u
Answer(s): (a) 12; (b) 22; (c) 11; (d) 10
