​A baseball player, over the course ​of a season, ​hit 38 home runs out of ​273 at-bats. ​Find the rate the baseball player hits home runs as a decimal rounded to the nearest thousandth.

A.7.184

B.0.861

C.0.139

D.0.162

The rate at which the baseball player hits home runs can be found by dividing the number of home runs (38) by the number of at-bats (273).

Dividing 38 by 273, we get: 38/273 ≈ 0.139.

Therefore, the rate at which the baseball player hits home runs as a decimal rounded to the nearest thousandth is 0.139.

The correct answer is C. 0.139.
