Answer 2

To solve the expression, let's perform the calculations step by step:

Step 1: Convert mixed numbers to improper fractions.

2 1/2 can be written as 5/2, 3 2/3 can be written as 11/3, 7 1/2 can be written as 15/2, and 7 1/3 can be written as 22/3.

Step 2: Perform the division inside the first parentheses.

(5/2 ÷ 11/3) = (5/2) * (3/11) = 15/22.

Step 3: Perform the division inside the second parentheses.

(15/2 ÷ 22/3) = (15/2) * (3/22) = 45/44.

Step 4: Perform the multiplication of the two fractions.

(15/22) * (45/44) = (15 * 45) / (22 * 44) = 675 / 968.

Step 5: Convert 5 1/4 to an improper fraction.

5 1/4 can be written as 21/4.

Step 6: Perform the final multiplication.

(675/968) * (21/4 * 4/21) = (675/968) * 1 = 675/968.

Therefore, the result of the expression is 675/968.
