Final answer:
By dividing the total number of baseball games (204) by the number of months in the season (17), we find that 12 games were played each month.
Step-by-step explanation:
To find out how many baseball games were played each month during a 17 month season with a total of 204 games, we would divide the total number of games by the number of months.
Divide 204 (the total number of games) by 17 (the total number of months).
Number of games each month = Total number of games / Number of months = 204 / 17 = 12
So, there were 12 baseball games played each month.
