Answer 2

To solve this 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).

Let's break down your expression step by step:

1. Start with the addition inside the parentheses: 2 1/3 + 2 2/3 = (2 + 1/3) + (2 + 2/3) = 2 + 1/3 + 2 + 2/3

2. Add the whole numbers and fractions separately: 2 + 2 + 1/3 + 2/3 = 4 + 1/3 + 2/3 = 4 + (1/3 + 2/3) = 4 + 1 = 5

So, the expression inside the parentheses equals 5.

3. Now, your expression becomes: 4.5 * 2.8 - 13 / 5

4. Perform the multiplication and division from left to right: 4.5 * 2.8 = 12.6 13 / 5 = 2.6

5. Finally, subtract the result of the division from the result of the multiplication: 12.6 - 2.6 = 10

So, the final result is 10.
