How about 1 gallon!
2 litre
50
As an approximation (only) a liter is about a quart, and a gallon is 4 quarts, therefore about one half.
no
No, its an approximation.
There are 128 fluid ounces in one US gallon. More in an Imperial gallon
1 qt 1 gallon = 4 quarts 1 quart = 0.25 gallon
The best approximation is, of course, the exact value. A reasonable approximation is 106.
What approximation is "best" depends on the required level of accuracy.
It is 60
There is no "best" approximation. The square root is irrational and so it is a non-terminating, non-recurring decimal so adding one more digit will always make it a better approximation.

With my 1980 g230 I get less than 10 miles to the gallon. This is an approximation but I believe that I get about 8 miles to the gallon in the city. It's very poor but still fun to drive.
which is the best approximation of
I'd say 2.1 or 2.
