Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Charlie spends
215 of his money on some marbles.
He spends
16 of his remaining money on some stickers.
- Amount that Charlie spends on the marbles = _____ u
- Amount that Charlie spends on the stickers = _____ u
- Amount that Charlie has in the end = _____ u
- Difference in the amount spent on the stickers and marbles = _____ u
(a)
Fraction of his money spent on the marbles =
215 Fraction of his money left after spending on the marbles
= 1 -
215=
1315 Fraction of his money spent on the stickers
=
1315 x

12901390 =
1390Amount that Charlie spends on the marbles = 12 u
(b)
Amount that Charlie spends on the stickers = 13 u
(c)
Amount that Charlie has in the end
= 90 u - 13 u - 12 u
= 65 u
(d)
Difference in the amount spent on the stickers and marbles
= 13 u - 12 u
= 1 u
Answer(s): (a) 12; (b) 13; (c) 65; (d) 1
