Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Adam spends
310 of his money on some beads.
He spends
35 of his remaining money on some marbles.
- Amount that Adam spends on the beads = _____ 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 beads = _____ u
(a)
Fraction of his money spent on the beads =
310 Fraction of his money left after spending on the beads
= 1 -
310=
710 Fraction of his money spent on the marbles
=
710 x
35=
2150Make the denominators the same.
310 =
15502150 =
2150Amount that Adam spends on the beads = 15 u
(b)
Amount that Adam spends on the marbles = 21 u
(c)
Amount that Adam has in the end
= 50 u - 21 u - 15 u
= 14 u
(d)
Difference in the amount spent on the marbles and beads
= 21 u - 15 u
= 6 u
Answer(s): (a) 15; (b) 21; (c) 14; (d) 6
