Answer 2

Let's break down the expression step by step:

1. First, simplify the fractions:

   • 2/5 can be written as 0.4 (since 2 divided by 5 is 0.4).
   • 1 1/4 can be written as 1.25 (since 1 whole plus 1/4 is 1.25).
   • 2 1/8 can be written as 2.125 (since 2 whole plus 1/8 is 2.125).

2. Now, perform the calculations within the parentheses:

   (1 + 0.4) / (2.125 + 3.4) - 0.33

3. Calculate the values within the parentheses:

   (1.4) / (5.525) - 0.33

4. Now, divide 1.4 by 5.525:

   1.4 / 5.525 ≈ 0.252

5. Finally, subtract 0.33 from the result:

   0.252 - 0.33 ≈ -0.078

So, the final result is approximately -0.078.
