Answer 2

Let's solve the expression step by step:

1. Perform the multiplication operations first: 2 × 3 × 7 = 42 4 × 52 = 208 22 ÷ 48 = 0.458333... (rounded to 6 decimal places)

2. Next, perform the division operations: 7 ÷ 9 ≈ 0.777777... (rounded to 6 decimal places) 208 ÷ 63 ≈ 3.301587... (rounded to 6 decimal places) 0.458333... ÷ 100 ≈ 0.004583 (rounded to 6 decimal places)

3. Now, combine the results and perform the addition and subtraction: 42 - 0.777777... + 3.301587... × 0.004583 + 100 + 12

4. Perform the remaining operations: 42 - 0.777777... + 0.015178 (rounded to 6 decimal places) + 100 + 12

5. Add up all the values: 42 + 100 + 12 - 0.777777... + 0.015178 (rounded to 6 decimal places)

Now, it's challenging to get the exact decimal representation of the result without a calculator. But, we can simplify the expression to its approximate value:

42 + 100 + 12 - 0.777777... + 0.015178 ≈ 153.238 (rounded to 3 decimal places)

So, the approximate value of the given expression is approximately 153.238.
