Just in case you are wondering what an earned run is as well, I figured I would give you the detailed answer.
The first thing you do is figure out the total innings pitched. The pitcher gets 1/3 of an inning counted for each out he pitches through.
Count up all runs unless the run was scored due to an error. Even if there was an error on the play, but the run would have scored anyway, it still counts as an earned run. If the run would never have crossed the plate without the error, then it is not counted.
Multiply the earned runs by 9 and then divide by the total innings pitched. Round off to the nearest hundredth.
Hope this helps.

ERA is Earned Run Average and is calculated by by taking the total earned runs and multiplying that by nine then dividing that by number of innings pitched.

you divide the number of innings that a player pitches and divide it by 9. From that number you divide the earned runs allowed.
12 divided by 9=1.3333
4 ER in 12 IP
4/1.3333=3.00 ERA is 3.00

earned runs / innings pitched *9
That "normalizes" the number to the equivalent of a complete game, for all pitchers.
The links below incude this information and much, much more.
