Batting Average (AVG): Divide the number of base hits by the total number of at bats.
If Tony Gwynn has 600 at bats and has 206 hits. His batting average would be .343 (206/600)
Earned Run Average (ERA): Multiply the total number of earned runs by nine, and divide the results by the total innings pitched. Randy Johnson has allowed 67 runs in 220 innings.
Multiply 67 by 9: 67x9=603. Divide 603 by 220 (his innings pitched): 603/220=2.74 -- which is his ERA
W-L percentage: Divide the number of games won by the total number of decisions.
Pedro Martinez has a 16-3 record, Divide his win total(16) by his total number of decisions: (19):16/19=0.842
Slugging Percentage (SLG): Divide the total number of bases of all base hits by the total number of times at bat.
Sammy Sosa has 282 total bases and 440 at-bats.
Divide 282 by 440 to get his slugging percentage: 282/440=.641
On-Base Percentage (OBP): Divide the total number of hits plus Bases on Balls plus hits by Pitch BY at Bats plus Bases on Balls plus hit by Pitch plus Sacrifice Flies
In Derek Jeter's 434 at-bats, he has 152 hits, 59 walks, has been hit by 9 pitches, and he's hit 6 sacrifice flies.
So here's the formula to determine his OBP:
(152+59+9)/(434+59+9+6)=220/508=.433
Fielding Average: Divide the total number of putouts and assists by the total number of putouts, assists and errors.
Edgardo Alfonzo has 218 putouts and 290 assists, while committing only 2 errors. So his fielding percentage is:
(218+290)/(218+290+2)=508/510=.996

I agree with the first guy that rounding the averages really messes the truth of the stat up to much. Let's just consider an example. Say a guy gets 400 at bats in a seson. And, let's say he got 125 hits. The way things are now, that would be a .313 average. If you round that to .31 you are taking you take one hit away! If you really round it down to .3, you take five hits away! I agree it's different compared to how we usually use decimals and percents, but for baseball it is simply more specific to use or show three places of accuracy.

Batting average is Hits/At Bats
Slugging average is Total Bases/AB
On Base Percentage is (Hits + Bases on Balls + Hit By Pitch)/(AB + BB + HBP + Sac. Flies)

Divide the number of base hits by the number of official at-bats.
One hit in four at-bats is .250
Three hits in 10 at-bats is .300
