Percents
[Page 2 of 36]
Percent means out of 100. We can use the percent symbol (%) as a handy way to write a fraction with a common denominator of 100. For example, instead of saying "8 out of every 100 professional basketball players are female," we can say "8% of professional basketball players are female."
A percent can always be written as a decimal, and a decimal can be written as a percent, by moving the decimal point two places to the right.

Most "applied arithmetic" concepts are variations of fractions.
The key to doing well on applied arithmetic questions is knowing how to set up the fractions.
Percents, as you probably know by now, are another way to express fractions. "Percent" just means "over 100." So to convert a percent into a fraction, just drop the % sign, place it over 100, and reduce the resulting fraction. To convert a fraction into a percent, multiply the fraction by 100 and add the percent sign.
So far, no problem. But now let's check out a more challenging type of percent question that you're sure to see on your exam.
