= 1 -
17 =
67 Fraction of remaining money after spending on the rulers
= 1 -
16 =
56 Fraction of what was left after spending on the markers
= 1 -
45 =
15 Fraction of money that was spent on markers =
47 (b)
Amount that Fanny spent on the folders = 1 u
Amount that Fanny spent on the markers = 4 u
Amount that the folders cost less than the markers
= 4 u - 1 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Amount that Fanny sent
= 1 u + 1 u + 4 u
= 6 u
= 6 x 3
= $18
Answer(s): (a)
47; (b) $18
