If a girl spends 3/7 of her money on food, 1/4 of her money on shoes and 1/3 of the remainder on a dress. how much money did she spend on the dress?
:
x = original amt of money
:
Find what fraction is left after buying food and shoes
x - 3%2F7x - 1%2F4x =
Common denominator is 28
28%2F28 - 12%2F28 - 7%2F28 = 9%2F28x remains
:
One third of that spent on the dress
1%2F3 * 9%2F28x = 9%2F84x, spent on the dress
