Answer:

9 boys in the school play

Step-by-step explanation:

Given that the ratio of boys to girls in the school play is 3:7, and there are a total of 30 students, we can find the number of boys by following these steps:


1. Calculate the total parts in the ratio: 3 (boys) + 7 (girls) = 10 parts in total.  


2. Determine the value of each part: Total students / Total parts = 30 students / 10 parts = 3 students per part.


3. Calculate the number of boys: 3 parts (boys) * 3 students per part = 9 boys in the school play.  Therefore, there are 9 boys in the school play.
