Hello, Sammy. 
 
Ok, the problem states that for every girl there are 3 boys.  So, in a class of 4 people, there will be one girl and three boys.  In a class of 8, there will be 2 girls and six boys, in a class of 12, there will be 3 girls and nine boys.  Now, one out of four is 25%.  So, the girls represent 25% of the class and boys represent 75%.  So, what you need to do is multiply the total number of students times the percentage that is made  up by boys.  This percentage must be represented as a decimal. So, this is what you have
(.75)(236)= 177 
 
There are 177 boys and 59 girls in the class.
 
I hope this helps out.
