Answer 2

Let's break down the expression step by step:

1. Calculate the value inside the parentheses: 1510 - (28 × 25) = 1510 - 700 = 810.

2. Now, we have the expression as follows: 306 : 208 + 81810 : 810.

3. Perform the divisions first:

   • 306 ÷ 208 ≈ 1.471153846 (rounded to several decimal places).
   • 81810 ÷ 810 ≈ 101 (rounded to the nearest whole number).

4. Now, we have the expression as follows: 1.471153846 + 101.

5. Add these two results together: 1.471153846 + 101 ≈ 102.471153846 (rounded to several decimal places).

So, the approximate value of the expression is approximately 102.471153846.
