How do you cross simplify?

Cross-simplification is a technique used to simplify the multiplication of fractions.

It is possible when the fractions have common factors that can be divided out.

For example the multiplication of the fractions 6/2 * 2/5 = (6*2)/(2*5). The 2's can be simplified out so that the multiplication is simply 6/1 * 1/5 = 6/5.
