(a)
Amount left after Adam spends on stickers and beads
= 1 -
121 -
37 = 1 -
121 -
921 =
1121Make the numerators the same.
1121 of the amount =
44 of the remaining amount
4484 of the amount =
4444 of the remaining amount
Amount that Adam spends on stickers =
121 =
484 Amount that Adam spends on beads =
37 =
3684 Amount that Adam spends on marbles
=
34 x 44 u
= 33 u
Amount that he has left
= 44 u - 33 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Amount that he spends on the stickers
= 4 u
= 4 x 3
= $12
(b)
Amount that he spends on the beads
= 36 u
= 36 x 3
= $108
(c)
Amount that he spends on the marbles
= 33 u
= 33 x 3
= $99
(d)
Amount that he spends altogether
= 12 + 108 + 99
= $219
Answer(s): (a) $12; (b) $108; (c) $99; (d) $219
