Numerator of a fraction

The numerator function allows the calculation of the numerator of a fraction.


A fraction is a number that is written as follows : `a/b` with a and b integers and b not zero. It's the quotient of a by b, that is to say : `a/b` = a:b. a is the numerator of the fraction and b is the denominator of the fraction. In other words, in a fraction, the numerator term is located above the stroke, the denominator is the end located below the stroke. The calculator with the numerator function used to find the numerator of a fraction or an expression with fractions.

  • Fraction numerator
  • The calculator is able to determine the numerator of a fraction : to find the fraction numerator of `4/5`, enter numerator(`4/5`), after calculation, the result `4` is returned.

    The calculator also applies to fractions that contain letters : to pour calculate the fraction numerator of `a/b`, enter numerator(`a/b`) , after calculation, the result `a` is returned.

    The numerator function is used on fractions but also to expressions containing fractions, after calculation, the simplified result is returned.

  • Numerator of an expression with fraction
  • When the numerator function is applied to an algebraic expression, the expression is first converted to a fraction, then the numerator of the fraction obtained is returned. So to find the numerator of the following expression `4/5+3/7`, enter numerator(`4/5+3/7`), after calculation, he fraction obtained is `43/35`, then the function returns the numerator `43`.

    The numerator function also applies to literal expressions.
