Determine the amount of fuel you wish to add, for example 10 L or 20 L. Add 1/50 that amount of oil. Note the oil slightly increases total volume.

10 L fuel, 0.2 L oil, 10.2 L total
20 L fuel, 0.4 L oil, 20.4 L total

It mixes best if you add the oil first, and use the flowing fuel to help mix the tank, but it is even better to add premixed.

Agreed, but ensure you do not draw neat oil into the fuel line, such as putting oil into an empty tank. The engine is guaranteed to stop if you do.
