K/D Ratio headache

[Kalgalath]

I'm really bad at math and I have a question about ratios in the games I play.

On COD Ghosts I currently have 6573 kills and 4817 deaths giving me a 1.37 K/D ratio.

Lets say from now till infinity, every game I play I get 10 kills and 10 deaths; will my K/D ratio drop and eventually even out to a 1.0? or will it never be any lower than 1.1?

What if from now till infinity I get 11 kills and 10 deaths, will my ratio continue to climb and will there ever be a point that it can go no further?

I'm all over the board but what i want to know is will i ever be able to hold a 2.0 as long as I continue to have at least 1 more kill than deaths?
