Reducible fraction

A reducible fraction is a ratio of two integers which have a common divisor. Thus, for example, is reducible because 2 divides both 10 and 14. On the other hand, is irreducible.

A fraction is no longer reducible or irreducible when the numerator and the denominator are relatively prime which means that the numerator and the denominator have a Gcd of 1.
