ring of fractions
noun
(algebra)
A
ring
whose
elements
are
fractions
whose
numerators
belong
to
a
given
commutative
unital
ring
and
whose
denominators
belong
to
a
multiplicatively
closed
unital
subset
D
of
that
given
ring.
Addition
and
multiplication
of
such
fractions
is
defined

(algebra) A ring whose elements are fractions whose numerators belong to a given commutative unital ring and whose denominators belong to a multiplicatively closed unital subset D of that given ring. Addition and multiplication of such fractions is defined just as for a field of fractions. A pair of fractions a/b and c/d are deemed equivalent if there is a member x of D such that x(ad-bc)=0.
The ring of fractions is a fundamental concept in algebra.
