In abstract algebra, the field of fractions of an integral domain is the smallest field in which it can be embedded. The construction of the field of fractions is modeled on the relationship between the integral domain of integers and the field of rational numbers. Intuitively, it consists of ratios between integral domain elements. The field of fractions of is sometimes denoted by or , and the construction is sometimes also calle…

Web(d)In the quotient ring Z[x]=(4,2x 1), we have the relations (I’ll sloppily omit the \bar" in the notation here) 4 = 0 and 2x 1 = 0, which together imply that 2 = 0, and hence (since 0 = 2x 1 = 0x 1 = 1) that 1 = 0, so 1 = 0. Thus the quotient ring is the zero ring, which means the ideal is the unit ideal, which is neither prime nor maximal.
