Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
310 of his money on some stickers.
He spends
34 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 =
310 Fraction of his money left after spending on the stickers
= 1 -
310=
710 Fraction of his money spent on the marbles
=
710 x
34=
2140Make the denominators the same.
310 =
12402140 =
2140Amount that Adam spends on the stickers = 12 u
(b)
Amount that Adam spends on the marbles = 21 u
(c)
Amount that Adam has in the end
= 40 u - 21 u - 12 u
= 7 u
(d)
Difference in the amount spent on the marbles and stickers
= 21 u - 12 u
= 9 u
Answer(s): (a) 12; (b) 21; (c) 7; (d) 9
