Question

Paul's car will go 49 kilometers on 7 tanks. Paul wants to know how fuel efficient the car is.

Answer 1

49 kms : 7 tanks
divide both sides by 7
equals
7 kms : 1 tank

Answer 2

Hello there,
Distance : Tanks
49           :   7
Since both sides are divisible by 7, 

Distance : Tanks
7             :    1

On side note: From what I have learnt, do not put any units (in this case km) when solving ratio

Hope this helps
