EXAMPLE:

A car can travel 350 km with 50 litres of petrol. How far would it be if the car was only filled with 20 litres of petrol?

SOLUTION:

50 litres = 350 km 20 litres = ___ km

\(\frac{350 \text{ km}}{50\text{ liter}}=\frac{?}{20\text{ liter}}\)

\(\frac{350}{50}\times{20}=140\)

20 litres = 140 km
