Work Step by Step
A shortcut allows you to find the lowest terms of the fraction step by step. For example
$\frac{6}{8} \cdot \frac{12}{2} = \frac{6}{2} \cdot \frac{3}{2} = \frac{3}{2} \cdot \frac{3}{1} = \frac{3 \cdot 3}{2 \cdot 1} = \frac{9}{2}$.
In each step we simplified the fractions by eliminating a common factor.
