Hey there!
For the first part of your question, you'll need more Ginger Ale than Sprite. You can see that you need 4.71 liters of Ginger Ale, which is a larger number than the 4.06 liters of Sprite that you need for the recipe.
Your three numbers going from least to greatest, just in case you need it for the other questions:
4.06, 4.69, 4.71
Hope this helped you out! :-)
