(a)
Amount left after Adam spends on marbles and beads
= 1 -
121 -
37 = 1 -
121 -
921 =
1121Make the numerators the same.
1121 of the amount =
55 of the remaining amount
55105 of the amount =
5555 of the remaining amount
Amount that Adam spends on marbles =
121 =
5105 Amount that Adam spends on beads =
37 =
45105 Amount that Adam spends on stickers
=
35 x 55 u
= 33 u
Amount that he has left
= 55 u - 33 u
= 22 u
22 u = 44
1 u = 44 ÷ 22 = 2
Amount that he spends on the marbles
= 5 u
= 5 x 2
= $10
(b)
Amount that he spends on the beads
= 45 u
= 45 x 2
= $90
(c)
Amount that he spends on the stickers
= 33 u
= 33 x 2
= $66
(d)
Amount that he spends altogether
= 10 + 90 + 66
= $166
Answer(s): (a) $10; (b) $90; (c) $66; (d) $166
