# You have a large container of olive oil. You have used 22-½ quarts of oil. Twentyfive percent of the olive oil remains. How many quarts of olive oil remain?

$22 \frac{1}{2}$ quarts would be 75% of the container
To find out what 25% would be we need to divide $22 \frac{1}{2}$ by 3
$22 \frac{1}{2} \div 3 = \frac{45}{2} \div \frac{3}{1} = \frac{45}{2} \times \frac{1}{3} = \frac{45}{6} = 7 \frac{1}{2}$
$7 \frac{1}{2}$ quarts remain
