Kathy spent
311 of her money on some rulers. She spent
18 of the remaining money on some glues and
47 of what was left on some highlighters.
- What fraction of her money was left?
- Given that the highlighters cost $27 more than the glues, find the sum of money that Kathy had at first.

(a)
Fraction of money left after spending on the rulers
= 1 -
311 =
811 Fraction of remaining money after spending on the glues
= 1 -
18 =
78 Fraction of what was left after spending on the highlighters
= 1 -
47 =
37 Fraction of money that was left =
311 (b)
Amount that Kathy spent on the glues = 1 u
Amount that Kathy spent on the highlighters = 4 u
Amount that the highlighters cost more than the glues
= 4 u - 1 u
= 3 u
3 u = 27
1 u = 27 ÷ 3 = 9
Amount that Kathy had at first
= 11 u
= 11 x 9
= $99
Answer(s): (a)
311; (b) $99
