-In statistics, the percentage is the same or equivalent to the proportion (p). Percent means per 100. For example, if there are 1,000 residents in a town, and 60% are Democrats, then, on average, 60 out of each 100 are Democrats. You determine the total number of Democrats by converting the percentage to a proportion, .60, and multiplying .60 x 1,000, which equals 600. -To determine a percentage, we divide the part by the whole and multiply by 100. So, if 8 out of 234 seniors are reported to have tried Meth, we calculate the percentage: 8/234 0.0342 and multiply 0.0342 x 100= 3.42%. -Remember: when you multiply by 10, move the decimal point one place to the right3; when you multiply by 100, move the decimal point two places to the right, etc. Answer the questions that follow the Table below Adolescents at three drug treatment centers were surveyed.
