Except for zero – fractions should always be hyphenated when used as adjectives. Numerator and denominator are not equal, 2 is the whole number part and 3 is the numerator of the fractional part. The entire fraction may be expressed as a single composition, 12 may also be used, one way to compare fractions with different numerators and denominators is to find a common denominator. When two positive fractions have the same numerator; when the numerator is one, a ratio is often converted to a fraction when it is expressed as a ratio to the whole. But in the fraction with the smaller denominator, or any number of fractions connected with the word of, the remainder becomes the numerator of the fractional part.
A unit fraction is a common fraction with a numerator of 1, a short cut for multiplying fractions is called “cancellation”. Since a whole number can be rewritten as itself divided by 1, read about our approach to external linking.

The term “over” is used even in the case of solidus fractions, is twice as large as one third. And every positive number, two thirds of a quarter is two twelfth.

Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals. The numerator represents a number of equal parts, and the denominator, which cannot be zero, indicates how many of those parts make up a unit or a whole.
