Final answer:

To multiply mixed numbers, convert each mixed number to an improper fraction, then multiply the numerators and denominators. Then, simplify the result if possible.

Step-by-step explanation:

A) To multiply mixed numbers, we first convert each mixed number to an improper fraction, then multiply the numerators and denominators. For example, 1 1/2 X 2 1/4 can be written as (3/2) X (9/4). Multiply 3/2 by 9/4 to get 27/8.

B) To multiply 2 1/3 X 3 1/2, convert each mixed number to an improper fraction, then multiply. 2 1/3 can be written as 7/3 and 3 1/2 can be written as 7/2. Multiply 7/3 by 7/2 to get 49/6.

C) 3 1/4 X 4 1/3 can be written as (13/4) X (13/3). Multiply 13/4 by 13/3 to get 169/12.

D) For 4 1/2 X 5 1/4, convert each mixed number to an improper fraction, then multiply. 4 1/2 can be written as 9/2 and 5 1/4 can be written as 21/4. Multiply 9/2 by 21/4 to get 189/8.
