We need to determine [tex]\frac{2}{5} * 16[/tex]. This is because [tex]\frac{2}{5}[/tex] is the cmount of paint used for one door, and we need to determine how much paint to use for 16 doors. In order to multiply a fraction by a whole number, we need to multiply the whole number and the numerator and keep the denominator.
[tex]\frac{2}{5} * 16 = \frac{32}{5} = 6\frac{2}{5}[/tex]
Therefore, you would need 30.4 gallons of paint to paint 16 doors.
