You have to divide both numerator (the upper number) and denominator (the downer number) by their Highest Common Factor (HCF). If their HCF is 1, you can't reduce : they are called COPRIME numbers.

E.g.

1) $$\frac{7}{21}=\frac{7\div7}{21\div7}=\frac{1}{3}$$

2)$$\frac{108}{216}=\frac{108\div108}{216\div108}=\frac{1}{2}$$

3)$$\frac{45}{150}=\frac{45\div15}{150\div15}=\frac{3}{10}$$
