Reducing Fractions
Fractions can be reduced if the numerator and denominator have a greatest common divisor(gcd) greater than 1. The gcd refers to the largest possible integer that will divide evenly into each value. For example, gcd(6,18) = 6, since 6/6 = 1 and 18/6 =3. Six is the largest integer that will divide evenly into each number. If this example were a fraction, we would have
6/18=(6/6)*(1/3)=1*1/3=1/3
