VULGAR FRACTION is a, part, or parts of an
A , ,
eighths. The upper number is ealled the numerator, and shews the part, or parts, expressed by the fraction; the lower number is called the denominator, and degotes the number of such parts contained in a unit.
Vulgar fractions are either proper, improper, compound, or mixt.
A proper fraction is one of which the numerator is less than the denomidator ; thus, , the
An improper fraction is one of which the numerator is equal to, or greater than, the denominator ; thus, s, $.
A compound fraction is, a fraction of a fraction ? as, of of Ź, &c.
A mixt number consists of a whole number and a fraction; as, 75.
A mixt fraction has a fraction annexed either to its numerator or denominator ; as, to or
REDUCTION OF VULGAR FRACTIONS.
RULE. Divide the greater term by the less, and that divisor by the remainder, till nothing be left : the last divisor will be the common measure ; by which divide both terms, for the fraction required.: Or,
Take the aliquot parts of both terms continually, till in their lowest terms. Note. If the common meafure be 1, the fraction is already in its lowest terms. Ciphers to the right hand of both terms may be rejecteds thus, 300=.
