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: $$3.3333333...$$
