Let s look at 25%. Put 25 over 100 to get y y. Notice that reduces to. It is good to be familiar with some of the common fraction and decimal equivalents of percentages. Some are listed in the chart below. 

Memorize some of the common fraction to decimal equivalents. 

The usual move from fractions to percents is through decimals — the decimal format is the middleman in the process. You probably already know some of the more common equivalences of percents and fractions. You know that 50 percent is equivalent to Vi and 25 percent is equivalent to A. Well, I m assuming that you know this, but, just in case, here are some properties and techniques that you can use to make the transitions easier. You don t have to memorize these properties, but having some of them in mind as you re working on percentage problems is helpful. 

Step 2 Recognize ht fractional part of the numerator of the new fraction as a common fraction. (The whole-number part does not matter.) Table A.l lists decimal fractions and their equivalents.
