The first thing that you do to solve these problems is to make sure that both of the terms are improper fractions.
Since 2 1/4 is a mixed number, you must convert it to an improper fraction.
The way you do this is by multiplying the wholes by the denominator and adding the numeration: 9
Keep the numerator to get your next problem of 9/4 times 1/3
Multiply the numerators and the denominators to get 9/12 which can be simplified into 3/4.
