Answer:
[tex]\frac38[/tex]
Step-by-step explanation:
Calculate total number of students: 9+15 = 24
[tex]Ratio=\frac{boys}{total}=\frac9{24}=\frac38[/tex]
3:8 is the answer I believe. You add 9 and 15 together, then you use 3 to simplify them both.
3 goes into 9, 3 times
3 goes into 24, 8 times
That is the simplest form
