Hey there!
Since, both terms goes into [tex]3[/tex], we have to divide by [tex]3[/tex] on each of your numbers that are in this particular word problem.
So, [tex]\frac{9}{3}[/tex][tex]=3[/tex] and [tex]\frac{15}{3}[/tex] [tex]= 5[/tex]
So, therefore this would be your answer [tex]\boxed{Answer:C.3:5}[/tex]
Good luck on your assignment and enjoy your day!
