(a)
Amount left after Adam spends on beads and marbles
= 1 -
120 -
310 = 1 -
120 -
620 =
1320Make the numerators the same.
1320 of the amount =
33 of the remaining amount
3960 of the amount =
3939 of the remaining amount
Amount that Adam spends on beads =
120 =
360 Amount that Adam spends on marbles =
310 =
1860 Amount that Adam spends on stickers
=
23 x 39 u
= 26 u
Amount that he has left
= 39 u - 26 u
= 13 u
13 u = 39
1 u = 39 ÷ 13 = 3
Amount that he spends on the beads
= 3 u
= 3 x 3
= $9
(b)
Amount that he spends on the marbles
= 18 u
= 18 x 3
= $54
(c)
Amount that he spends on the stickers
= 26 u
= 26 x 3
= $78
(d)
Amount that he spends altogether
= 9 + 54 + 78
= $141
Answer(s): (a) $9; (b) $54; (c) $78; (d) $141
