Answer:
234
Step-by-step explanation:
So what we know is that 
5x+9x= students
This equation is saying that for every 5 boys there are 9 girls 
we can then plug in 364 for the number of students and add like terms
This means that 14x=364
this means that x=26
This means that there are 26 sets of 5 boys and 9 girls 
this means that there are 
130 boys 
234 girls
