At the last school pep rally, 4 out of every 9 students wore school colors. Based on this information, if 450 students attend the next pep rally, how many of these students will wear school colors?

So, here's the ratio:

4:5 (I got 5 because 9 - 4 = 5)

We can add variables to these and make an equation:

9n = 450

n = 450/9

n = 50

50*4 = 200

200 students will wear school colors.

The ratio of students is 4:5, with 4 students out of every 9 wearing colors and 5 not. Use this ratio to solve: how many students out of 450 are wearing the colors? First divide by 9 to get 50, then multiply by 4. The answer is 200.
