To make it more clear, this is what I need help with.



KM at first fillup: (textbox)
KM at last fillup: (textbox)
Litres at last fillup: (textbox) CALCULATE
Consumption: (textbox) Litre/100KM

so add 3 NumericUpDown controls and name them:
nudKMFirst
nudKMLast
nudLitres

for all three NumericUpDown controls, set the Decimal property to 4 to allow 4 digits after the decimal point

also add a Label, i'd name it: lblResults
then add a button and name it btnCalculate
now all you need to do is is calculate the Consumption

since this sounds like homework, i've given you a start but it's up to you to show your attempts at the calculation(s)
