Explanation:

Step1: Choose the conversion ratio

We need to convert gallons to liters. The ratio that relates gallons and liters is $\frac{3.79\ L}{1\ gal}$.

Step2: Perform the conversion

Multiply the number of gallons ($39\ gal$) by the conversion ratio:
$$\frac{39\ gal}{1}\times\frac{3.79\ L}{1\ gal}$$
The "gal" units cancel out. Then calculate $39\times3.79 = 147.81$.

Answer:

$\frac{39\ gal}{1}\times\frac{3.79\ L}{1\ gal}= 147.81\ L$
