Give the answers in units (Eg 1 u) or unit equations (Eg 1 u +2).
Bryan spends
314 of his money on some marbles.
He spends
13 of his remaining money on some beads.
- Amount that Bryan spends on the marbles = _____ u
- Amount that Bryan spends on the beads = _____ u
- Amount that Bryan has in the end = _____ u
- Difference in the amount spent on the beads and marbles = _____ u
(a)
Fraction of his money spent on the marbles =
314 Fraction of his money left after spending on the marbles
= 1 -
314=
1114 Fraction of his money spent on the beads
=
1114 x
13=
1142Make the denominators the same.
314 =
9421142 =
1142Amount that Bryan spends on the marbles = 9 u
(b)
Amount that Bryan spends on the beads = 11 u
(c)
Amount that Bryan has in the end
= 42 u - 11 u - 9 u
= 22 u
(d)
Difference in the amount spent on the beads and marbles
= 11 u - 9 u
= 2 u
Answer(s): (a) 9; (b) 11; (c) 22; (d) 2
