What is the logic to calculate the percentage of victory, draw and defeat?

I'm wondering the logic, how to calculate the percentage of tables in a football game.

For example, I put here a quick Excel desktop just for demonstration. In red is the actual percentage, and next to it is the percentage that I have achieved.

So my question is how to reach 100% when you win all, 77% when you win 2 and draw 1 and when you get 44% when you win 1, you tie 1 and you lose 1.

What logic is used in this calculation? I tried to break my head but this time, but I did not get results.

To calculate the percentage in this case, with 3 elements, you calculate the difference of the item you are looking for in relation to the total sum. Ex:

  • 3 wins
  • 4 defeats
  • 1 tie

To know the% of victories : 

3 / (3 + 4 + 1)
3 / 8
0,375
37,5% de vitórias

To know the% of defeats : 

4 / (3 + 4 + 1)
4 / 8
0,5
50% de derrotas

To know the% of ties : 

1 / (3 + 4 + 1) * 100
1 / 8
0,125
12,5% de derrotas

Logo: 

37,5% + 50% + 12,5% = 100%
