FRACTIONS.

FRACTIONS, or broken numbers, are expressions for any assignable part of an unit or whole number, and (in general) are of two kinds, viz.

VULGAR AND DECIMAL.

A Vulgar Fraction, is represented by two numbers placed one above another, with a line drawn between them, thus,,, &c. signifies three-fourths, five-eights, &c.The figure above the line, is called the numerator, and hat below it, the denominator,

Thus,

Denominator.
S5 Numerator.

The denominator (which is the divisor in division) shews how many parts the integer is divided into; and the numerator (which is the remainder after division) shews how many of those parts are meant by the fraction.

A fraction is said to be in its least or lowest terms, when it is expressed by the least numbers possible, as when reduced to its lowest terms will be, and is equal to 3, &c.

PROBLEM I.

ΤΣ

10. Reduce 5184 to its lowest terms.

PROBLEM II.

75

To find the value of a fraction in the known parts of the integer, as to coin, weight, measure, &c.
