Answer:
2.5 gallons
Step-by-step explanation:
Make the denominators of the fractions the same and combine them
![\frac{1}{3} =\frac{2}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%3D%5Cfrac%7B2%7D%7B6%7D)
![\frac{2}{6} +\frac{1}{6} =\frac{3}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B6%7D%20%2B%5Cfrac%7B1%7D%7B6%7D%20%3D%5Cfrac%7B3%7D%7B6%7D)
Then simplify the fraction
![\frac{3}{6} =\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B6%7D%20%3D%5Cfrac%7B1%7D%7B2%7D)
Then subtract how many gallons you have from how many you want
![3 -\frac{1}{2} = 2\frac{1}{2}](https://tex.z-dn.net/?f=3%20-%5Cfrac%7B1%7D%7B2%7D%20%3D%202%5Cfrac%7B1%7D%7B2%7D)
You will need 2.5 gallons to make 3 gallons
