Probability question

Kaylee has 2 gallons each of red and blue paint, and 1 gallon each of orange and green paint. She paints her bedroom with these jars of paint. If she uses $\frac{2}{3}$ of the red paint, $\frac{1}{4}$ of the blue paint, $\frac{1}{2}$ of the orange paint, and $\frac{5}{7}$ of the green paint, how much paint (in gallons) does Kaylee have left over?
