The pie chart shows the percents of students that play various sports at a school with 1800 students. Determine how many students play lacrosse.
Since 20 percent play lacrosse of the 1800 students, we need to multiply 20 percent times 1800.
To make 20 percent into a decimal, we take 20, divide by 100, and get rid of the percentage sign, which is equal to 0.20 times 1800, which is equal to 360. So out of the 1800 students, 360 students play lacrosse.
