Answer 2

Let's break down the expression step by step:

1. First, simplify the numerator:

   3.25 - (-0.8) - 3.25 - 0.2

   = 3.25 + 0.8 - 3.25 - 0.2

   = 4.05 - 3.45

   = 0.6

2. Next, simplify the denominator:

   0.5 / (0.4 - (-2 1/3))

   To subtract the fractions in the denominator, we need to find a common denominator. The common denominator for 0.4 and -2 1/3 is 3. So, we'll convert 0.4 to a fraction with a denominator of 3:

   0.4 = 4/10 = 2/5

   Now, the denominator becomes:

   2/5 - (-2 1/3)

   To subtract fractions, we need to have the same denominator. The common denominator for 2/5 and -2 1/3 is 15. So, let's convert both fractions to have a denominator of 15:

   2/5 = (2/5) * (3/3) = 6/15

   -2 1/3 = -(2 + 1/3) = - (6/3 + 1/3) = - (7/3)

   Now, the denominator is:

   6/15 - (-7/3)

   = 6/15 + 7/3 (since adding the negative is the same as subtracting a negative)

   To add these fractions, we also need a common denominator, which is 15:

   (6/15) + (7/3) = (6/15) + (35/15)

   = 41/15

3. Now, divide the numerator by the denominator:

   (0.6) / (41/15)

   To divide by a fraction, multiply by its reciprocal:

   (0.6) * (15/41)

   Now, multiply the numerators and denominators:

   (0.6 * 15) / 41

   = 9 / 41

So, the final result is 9/41.
