Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
313 of his money on some stickers.
He spends
23 of his remaining money on some marbles.
- Amount that Adam spends on the stickers = _____ u
- Amount that Adam spends on the marbles = _____ u
- Amount that Adam has in the end = _____ u
- Difference in the amount spent on the marbles and stickers = _____ u
(a)
Fraction of his money spent on the stickers =
313 Fraction of his money left after spending on the stickers
= 1 -
313=
1013 Fraction of his money spent on the marbles
=
1013 x
23=
2039Make the denominators the same.
313 =
9392039 =
2039Amount that Adam spends on the stickers = 9 u
(b)
Amount that Adam spends on the marbles = 20 u
(c)
Amount that Adam has in the end
= 39 u - 20 u - 9 u
= 10 u
(d)
Difference in the amount spent on the marbles and stickers
= 20 u - 9 u
= 11 u
Answer(s): (a) 9; (b) 20; (c) 10; (d) 11
