Simplifying 5/13

How to reduce 5/13 to its simplest form

To simplify 5/13 we have to divide both numerator (5) and denominator (13) by their greatest common factor (GCF). In other words, writing a fraction in its simplest form means that both numerator and denominator can no longer be divided by the same whole number other than 1.
