Because of their broad applicability to real life, percent problems are common in standardized tests. We calculate percents every day, from leaving fair tips at restaurants to figuring out which sale will save the most money. While the percent problems on the GRE quantitative<\/a> may be a little more complicated than those everyday calculations, they all follow the same basic rules.

Converting Decimals to Percents<\/h3>
<\/div><\/div><\/div>
\nThe word \u2018percent\u2019 literally means hundredth, so 19% really means 19 hundredths, and can be written as either .19 or 19\/100. So, if you want to convert a decimal to a percent, simply move the decimal point two places to the left. While converting .19 to 19 percent may seem intuitive, the two-decimal-point rule will come in handy when you must convert .00031 to a percent (.031%). To convert that percent to a decimal, just move the decimal two points to the left.
