Question 14251: I have a quiz tomorrow and I have a question that I can't figure out what the equation is, Tech High School surveyed it's freshmen and found that three fourths of the freshmen own an iPod. If 240 freshmen have iPods, how many freshmen attend Tech High?

Let x = the number of Freshmen. Set up the equation as follows:
%283%2F4%29x+=+240 Solve for x by multiplying both sides by the multiplicative inverse of 3/4, which is 4/3.
x+=+240%284%2F3%29
x+=+320
320 Freshmen attend Tech High.
