Answer:
5 gallons
Step-by-step explanation:
Unit conversion (given) : 1 gallon = 3.785 liters
Here, we are given 18 liters.
Then, let the value in gallons be x. We can take the values in proportion.
⇒ [tex]\frac{x}{1} = \frac{18}{3.785}[/tex]
⇒ [tex]x = \frac{18}{3.785}[/tex]
⇒ [tex]x = 4.75561427[/tex]
⇒ x = approximately 5 gallons
