Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
15 of his money on some marbles.
He spends
13 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 =
15 Fraction of his money left after spending on the marbles
= 1 -
15=

315415 =
415Amount that Adam spends on the marbles = 3 u
(b)
Amount that Adam spends on the stickers = 4 u
(c)
Amount that Adam has in the end
= 15 u - 4 u - 3 u
= 8 u
(d)
Difference in the amount spent on the stickers and marbles
= 4 u - 3 u
= 1 u
Answer(s): (a) 3; (b) 4; (c) 8; (d) 1
