(a)
Amount left after Adam spends on beads and marbles
= 1 -
121 -
37 = 1 -
121 -
921 =
1121Make the numerators the same.
1121 of the amount =
33 of the remaining amount
3363 of the amount =
3333 of the remaining amount
Amount that Adam spends on beads =
121 =
363 Amount that Adam spends on marbles =
37 =
2763 Amount that Adam spends on stickers
=
23 x 33 u
= 22 u
Amount that he has left
= 33 u - 22 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Amount that he spends on the beads
= 3 u
= 3 x 3
= $9
(b)
Amount that he spends on the marbles
= 27 u
= 27 x 3
= $81
(c)
Amount that he spends on the stickers
= 22 u
= 22 x 3
= $66
(d)
Amount that he spends altogether
= 9 + 81 + 66
= $156
Answer(s): (a) $9; (b) $81; (c) $66; (d) $156
