Answer: 312 students
Step-by-step explanation: We know that Jackson Middle School has 6 students in the choir for every 1 student in band.
So we can set up the ratio 6 choir/1 band.
We want to find out how many students are in the choir at Jackson Middle School if there are 52 students in the band.
So using the same ratio of choir/ban on the other side of the proportion, we have x choir/52 band where <em>x</em> represents the number of students that are in the choir at Jackson Middle School.
So we have the proportion 6 choir/1 band = x choir/52 band.
Now we can use cross products to find the missing value in this proportion.
So we have (6)(52) or 312 equals 1 times x or <em>x</em>.
If you'd like to, you can always put a 1 in front of the variable.
So now we have the equation 312 = x.
This means that for 52 students in the band, there are 312 students in the choir at Jackson Middle School.
