Final answer:
To find the number of parents who attended the soccer game, multiply the total number of attendees by 0.60.
Step-by-step explanation:
To find the number of parents who attended the soccer game, we need to determine 60% of the total number of attendees. We can do this by multiplying the total number of people by 0.60:
Number of parents = 120 x 0.60 = 72
Therefore, there were 72 parents who attended the soccer game.
