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: \(3.3333333...\)
