Answer 3

To solve the expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In this expression, you don't have any exponents or parentheses/brackets, so you'll perform the operations in the following order:

1. First, calculate the division inside the parentheses:

   0.824 + 1.176 = 2.000

2. Now, you have:

   7.72 × 2 1/4 - 4.06 ÷ 2.000

3. Next, convert the mixed number "2 1/4" to an improper fraction:

   2 1/4 = 9/4

4. Now, you have:

   7.72 × 9/4 - 4.06 ÷ 2.000

5. Perform the multiplication and division from left to right:

   7.72 × 9/4 = 17.37 (approximately) 4.06 ÷ 2.000 = 2.03

6. Now, the expression becomes:

   17.37 - 2.03

7. Finally, subtract:

   17.37 - 2.03 = 15.34

So, the result of the expression is approximately 15.34.
