Question

In Europe gasoline is often sold in liters. If a typical fill-up requires 11 gal of gas, how many liters are necessary?

Answer 1

Answer:

41,64 liters

Explanation:

In order to change the units we need to know the equivalence of said units.

1 gal of gas equals to 3,78541 liters.

We can use cross-multiplication in order to convert it into liters:

$\frac{1 gal}{3.78541 L} = \frac{11 gal}{X}  \\\\X= \frac{3.78541 L x 11 gal}{1 gal}$

A typical fill-up requires 41,64 liters.
