odds question

[orig!naL]

I was reading something on 2+2 and I didn't fully understand where a couple numbers are coming from. I understand odds, but I just want to know if I'm missing something here:

Where is this coming from? 100/3.22 = 31.06. (So we need 31% equity to call. Where is the 100/3.22 coming from?)

You’re UTG with 65s. You open to $7. Two folds to Nit on the button. Nit makes a pot 3bet to $24. You make a pot 4bet to $75. Nit 5bets all in.

Pot Odds:
You have to call $125 to win a pot of $278. You’re getting 278:125, or 2.22:1.

100/3.22 = 31.06. (WHERE IS THE 100 / 3.22 COMING FROM)

Equity:

equity win tie pots won pots tied
Hand 0: 22.496% 22.29% 00.20% 18321336 168354.00 { 65s }
Hand 1: 77.504% 77.30% 00.20% 63532548 168354.00 { KK+ }

Are you priced in to call?

No. You need a little over 31% equity to call, and you only have about 22.5%. You can fold the hand without making a mistake.
