Simplifying 4/15

How to reduce 4/15 to its simplest form

To simplify 4/15 we have to divide both numerator (4) and denominator (15) 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.
