For CDG-GVA you would get the percentage of 750 corresponding to your fare class. So if you're in V you would get 25% of 750.
For ATL-MCO it depends on your flight number: if you're flying under AF/KL code the base mileage is 750, if you're flying under DL code it is 500. In this case the percentage corresponding to your fare would be applied as well.
You can get this information from the mileage calculator on the FB website.
