Final answer:
The expression (4 5/4 * 4 1/4) is equivalent to 357/16.
Step-by-step explanation:
The expression (4 5/4 * 4 1/4) can be simplified as follows:
First, we need to convert the mixed numbers to improper fractions. So, 4 5/4 becomes (4 * 4) + 5 = 21/4 and 4 1/4 becomes (4 * 4) + 1 = 17/4.
Now, we can multiply the two fractions: (21/4) * (17/4) = (21 * 17) / (4 * 4) = 357/16.
Therefore, the expression (4 5/4 * 4 1/4) is equivalent to 357/16.
