Opening Day for Baseball -- Go A's! & Go Giants!

Try out some baseball math to celebrate the occasion.

Batting average (avg): Divide the number of base hits by the total number of at bats. Example: If Ichiro has 400 at bats and has 157 hits, his batting average would be .393. (157 hits/400 bats = .393)

Earned Run Average (ERA): Multiply the total number of earned runs by nine, and divide the results by the total innings pitched. Example: Felix Hernandez allows 3 earned runs in 8 innings for an ERA of 3.38. (3 runs x 9 innings=27, 27/8 innings = 3.38) Note: If a pitcher pitches 1/3 or 2/3s of an inning, it’s calculated by .1 or .2, or if Felix pitched 6 2/3 innings, it would calculated as 6.2 innings.

Try these two word problems and leave the answers in the comments section.  (Don't peek at other students' answers first!)
1.  If Matt Cain pitched 7 innings and gave up 2 earned runs, what was his ERA for that game?
2.  If Coco Crisp has 134 hits in 413 at bats, what is his batting average for the season?
