Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
213 of his money on some marbles.
He spends
14 of his remaining money on some stickers.
- Amount that Adam spends on the marbles = _____ u
- Amount that Adam spends on the stickers = _____ u
- Amount that Adam 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 =
213 Fraction of his money left after spending on the marbles
= 1 -
213=
1113 Fraction of his money spent on the stickers
=
1113 x
14=
1152Make the denominators the same.
213 =
8521152 =
1152Amount that Adam spends on the marbles = 8 u
(b)
Amount that Adam spends on the stickers = 11 u
(c)
Amount that Adam has in the end
= 52 u - 11 u - 8 u
= 33 u
(d)
Difference in the amount spent on the stickers and marbles
= 11 u - 8 u
= 3 u
Answer(s): (a) 8; (b) 11; (c) 33; (d) 3
