At the last football game, 4 out of every 9 students wore school colors. based on this information, if 450 students attend the next football game, how many students will wear school colors?

To complete this problem, you want to set a proportion.  So, what you know is that 4 every 9 students wore school colors are important.  Think of it like a key, or scale.  And the number you want to figure out is if 450 attend, how many will wear the school colors. What number does 450 relate to, and which does the unknown relate to?  What are you trying to figure out? Then you put that in proportion form with one fraction equaling a number.  If you don't know how to solve a proportion, I can explain that if you want.  If you have any further questions, just ask:)
