Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
16 of his money on some marbles.
He spends
12 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 =
16 Fraction of his money left after spending on the marbles
= 1 -
16=
56 Fraction of his money spent on the stickers
=

212512 =
512Amount that Adam spends on the marbles = 2 u
(b)
Amount that Adam spends on the stickers = 5 u
(c)
Amount that Adam has in the end
= 12 u - 5 u - 2 u
= 5 u
(d)
Difference in the amount spent on the stickers and marbles
= 5 u - 2 u
= 3 u
Answer(s): (a) 2; (b) 5; (c) 5; (d) 3
