For example, a fraction is put in lowest terms by cancelling out the common factors of the numerator and the denominator. [2] As another example, if a×b=a×c, then the multiplicative term a can be canceled out if a≠0, resulting in the equivalent expression b=c; this is equivalent to dividing through by a.
In mathematics, division by zero, division where the divisor (denominator) is zero, is a unique and problematic special case. Using fraction notation, the general example can be written as a 0 {\displaystyle {\tfrac {a}{0}}} , where a {\displaystyle a} is the dividend (numerator).
Most decimal fractions (or most fractions in general) cannot be represented exactly as a fraction with a denominator that is a power of two. For example, the simple decimal fraction 0.3 ( 3 ⁄ 10 ) might be represented as 5404319552844595 ⁄ 18014398509481984 (0.299999999999999988897769…).
This works because the cancellation in the numerator ( (+)) = ^ + (^) and the cancellation in the denominator ^ = (+) counteract each other; the function = (+) / is well-enough conditioned near zero that (^) gives a good approximation to (), and thus (^) gives a good approximation to = (+).
The irreducible fraction for a given element is unique up to multiplication of denominator and numerator by the same invertible element. In the case of the rational numbers this means that any number has two irreducible fractions, related by a change of sign of both numerator and denominator; this ambiguity can be removed by requiring the ...
