Answer 2

To solve this expression, you can 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 case, you'll want to first perform the multiplications and divisions and then the additions and subtractions.

Let's break it down step by step:

1. Calculate the multiplications and divisions:

   • $6 \frac{1}{4} \times 8 = 6.25 \times 8 = 50$
   • $3 \frac{2}{3} \times 5 \frac{1}{2} = 3.67 \times 5.5 ≈ 20.185$
   • $2 \frac{2}{5} \times 4 \frac{7}{12} = 2.4 \times 4.5833 ≈ 11.00$

2. Now, you can add and subtract the results:

   $50 - 20.185 + 11.00$

3. Perform the remaining operations:

   $50 - 20.185 + 11.00 = 29.815 + 11.00 ≈ 40.815$

So, the result of the expression is approximately $40.815$.
