A fraction is said to be “irreducible” if the numerator and denominator are relatively prime, i.e. if the numerator and denominator have no common divisor.  For example, the fraction 2/3 is irreducible, whereas the fraction 4/6 is “reducible” (and in fact it can be reduced to 2/3).   1.Consider the set of fractions {}.   How many of these fractions are irreducible?   2. Consider the set of fractions {}.     How many of these fractions are irreducible?
