Question

Lily's car has a fuel efficiency of 888 liters per 100 kilometers.

Answer 1

Lily's car fuel efficiency in kilometers per liter is 25 kilometers per 222 liters

Solution:

Given, Lily's car has a fuel efficiency of 888 liters per 100 kilometers.  

We have to find what is the fuel efficiency of Lily's car in kilometers per liter?

Now, fuel efficiency in liters per kilometer = $\frac{888}{100}$

We know that, fuel efficiency in kilometers per liter is $=\frac{1}{\text { fuel efficiency in lieters per kilometers }}$

$=\frac{1}{\frac{888}{100}}$

$=\frac{1}{1} \times \frac{100}{888}=\frac{100}{888}$

$=\frac{25}{222}$

We can stop here as there is no factor to cancel

Hence, fuel efficiency in kilometers per liter is 25 kilometers per 222 liters.
