Question

At Southside Middle School, 20% of the students play an instrument. There are 305 students. How many students play an instrument?

Answer 1

you could start by doing 305 x 20% to see what you get

Answer 2

To explain what breshay did, we know there are 305 students. Since the question says 20% of students play instruments, we would do 305*20% to find the 20% of the students who play an instrument. 20 % is .20 in decimal form.
