I am studying fractions and how to calculate them and the terms numerator and denominator appear a lot when I read about it, but I do not know the numerator and denominator definition.


$$ \frac{4}{2} + \frac{8}{2} = \frac{4+8}{2} = \frac{12}{2} $$

Would I like to know your definition?

  • $\begingroup$ Have you tried asking the internet to define numerator? $\endgroup$ – Ethan Bolker Sep 1 '18 at 14:11
  • $\begingroup$ @EthanBolker I tried, but the explanations are complicated for me and I could not understand. $\endgroup$ – gato Sep 1 '18 at 14:14

In the fraction $$\frac{p}{q}$$ where $q\ne 0$

$p$ is called Numerator and $q$ is called denominator

  • $\begingroup$ $q$ can be less than zero $q<0$ ? $\endgroup$ – gato Sep 1 '18 at 14:22
  • $\begingroup$ It can, but this is generally considered an improper fraction (which might matter or not). You can always change the signs of both denominator and numerator to get an equal fraction, equally in its lowest terms $\endgroup$ – Deepesh Meena Sep 1 '18 at 14:24
