No problem.
To answer your question: because we just do.
Seriously, though, it just has to do with converting percentage to ratio.
Honestly, I don't know if I can explain it correctly but I'll do my best.
Lets say a pot is $100 after your opponent bet $25. You need to call $25 to win $100. Using the ratio method, we can see its: $100:$25 or 4:1 pot odds.
4:1 = 20% chance of hitting. Out of 5 [4+1] tries, you win 4, lose 1.
However, $25 is not 20% of $100, it's 25%. So, in order to make sure our ratio method and percentage method are the same, we must include our call with the pot. So, $25 is 20% of $125.
