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 the expression step by step:

1. Start with the division inside the parentheses:

   (11.25 - 35/12 + 4.3 - 719/30) / (77/12 - 55/6)

2. Next, calculate the values within each set of parentheses:

   (11.25 - 2.9167 + 4.3 - 23.9667) / (6.4167 - 9.1667)

3. Continue by performing the subtraction and addition operations within each set of parentheses:

   (11.25 - 2.9167 + 4.3 - 23.9667) / (-2.75)

4. Now, perform the operations from left to right within the numerator:

   11.25 - 2.9167 = 8.3333 8.3333 + 4.3 = 12.6333 12.6333 - 23.9667 = -11.3334

5. Calculate the division in the numerator:

   (-11.3334) / (-2.75) = 4.1214 (rounded to four decimal places)

So, the result of the expression is approximately 4.1214.
