Answer 2

Let's break down this expression step by step:

1. Simplify fractions within parentheses:

   • 3/6 simplifies to 1/2.
   • 1/4 remains the same.

2. Calculate the values within parentheses:

   • (1/2 - 1/4) = 1/4
   • (1.3/5 - 3/10) = (0.26 - 0.3) = -0.04
   • (1/4 - 1/8) = (2/8 - 1/8) = 1/8

3. Substitute the simplified values back into the expression: 2/3 + 1.1/2 - 1/4(1/2 - 1/4) + (1/4)(-0.04) + (1/8)

4. Now, calculate the products within parentheses and add/subtract the fractions:

   • 1/4(1/2 - 1/4) = 1/4(2/8 - 1/8) = 1/4(1/8) = 1/32
   • (1/4)(-0.04) = -1/4 * 0.04 = -1/25

5. Combine like terms: 2/3 + 1.1/2 + 1/32 - 1/25 + 1/8

6. To add fractions with different denominators, find a common denominator, which in this case is 120:

   • Multiply 2/3 by 40/40 to get 80/120.
   • Multiply 1.1/2 by 60/60 to get 66/120.
   • 1/32 remains the same.
   • Multiply -1/25 by -4.8/4.8 to get 192/120.
   • Multiply 1/8 by 15/15 to get 15/120.

7. Now, add the fractions with the common denominator: 80/120 + 66/120 + 1/32 - 192/120 + 15/120

8. Add the fractions together: (80 + 66 + 1 - 192 + 15)/120

9. Calculate the numerator: 80 + 66 + 1 - 192 + 15 = -30

10. Final fraction: (-30/120)

11. Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 30: (-30/120) = (-1/4)

So, the value of the expression is -1/4.
