First, let's review vocabulary pertaining to FRACTIONS and closely related concepts. FRACTION—part of a whole, any number of equal parts NUMERATOR—top number of a fraction, the number of parts taken from the whole DENOMINATOR—bottom number of a fraction, the number of parts into which a whole is divided DIVISION BAR, also known as FRACTION BAR—the line that separates the numerator and denominator UNIT FRACTION—a fraction where one part is taken from the whole, e.g.,_{}PROPER FRACTION—a fraction whose numerator is smaller than the denominator, e.g.,_{}IMPROPER FRACTION—a fraction whose numerator is larger than the denominator, e.g._{}MIXED FRACTION, also known as MIXED NUMBER—a combination of a WHOLE NUMBER and a PROPER FRACTION, e.g.,_{}_{}DECIMAL—a fraction whose denominator is a power of ten and whose numerator consists of the digits following the DECIMAL POINT (dot or period), e.g., 0.4 (equivalent to_{}_{}) PERCENT—a decimal number multiplied by 100 and suffixed with the percent sign (%), e.g., 40% EQUIVALENT FRACTIONS—two or more fractions whose numerators and denominators are different, but give the same value when simplified LOWEST TERMS—the simplified form of a fraction## Here are different ways of representing a fraction:

## SIMPLIFYING FRACTIONS

The process of simplifying fractions consists in dividing both numerator and denominator of the fractions by the GREATEST COMMON FACTOR or GCF.
