How to convert KM per L to L per 100 KM

Say the dial on our car says  8.4KM per L (1L) and want to convert this to L per 100 KM the formula to conver this is

Litre Used  / Distance in KM driven  * 100

1 L / 8.4 KM *100

1 / 8.4 * 100 = 11.9047619047619

Rounded down that 11.9L per 100KM

Let's try another example;

Say we had driven 557KM on 74 Liters  of fuel this would be

Litre / Distance * 100

74 / 557 * 100  = 13.28545780969479

Rounded down 13.2 Liters per 100  KM.
