How do I solve this?

We're working on Dimensional Analysis in my chemistry class, and I encountered this problem in my workbook. I can't figure it out. I've never been good at these types of problems, please help.

24) A baseball player's batting average is 0.254 (254 hits per 1000 at bats). If she is at bat an average of 3 times per game, how many hits will she make in 52 games? Show your work.

grr, I feel so stupid

Uhh... well she hits 254 for each 1000 times she bats. In this scenario, she will bat 156(52 * 3) times.

156 * .254 = 39.6 hits which rounds down to 39 hits(Because half a hit =/= a hit)

Now we check.

39.6/156 = .253

So she will hit the ball 39 times in 156 bats.
