You want to Cross Multiply. :)

Think of the whoe number as a fraction.  The whole number is the numerator and the dominator is 1.  Then multiply the numerators togother and multiply the dominators togother.  Then if possible, reduce the fraction.

Example:

$5\times\frac{2}{3}$

$\frac{5}{1}\times\frac{2}{3}$

In Improper form: $\frac{10}{3}$

In mixed form:  $3\frac{1}{3}$

In decimal form: $3.3333333...$
