Answer 3

Let's break down the expression step by step:

1. First, let's simplify the expression inside the parentheses: 1 5/6 × 3/11 + 8/25 ÷ 0.4

2. Convert the mixed fraction to an improper fraction: 1 5/6 = (6 × 1 + 5) / 6 = 11 / 6

3. Perform the multiplication and division operations: (11 / 6) × (3 / 11) + (8 / 25) ÷ 0.4

4. Cancel out the common factor between the numerator and denominator of the first fraction: (1) × (1 / 6) + (8 / 25) ÷ 0.4

5. Perform the addition and division operations: 1/6 + (8 / 25) ÷ 0.4

6. Convert the whole number 1 to a fraction with a denominator of 6: 1 = 6 / 6

7. Find a common denominator for the fractions: The common denominator for 6 and 25 is 150.

8. Convert all fractions to have a denominator of 150: (6 / 6) × (25 / 25) × (1 / 6) + (8 / 25) × (6 / 6)

9. Perform the multiplication in each fraction: (150 / 150) × (25 / 150) + (48 / 150)

10. Perform the addition: (25 / 150) + (48 / 150) = (25 + 48) / 150 = 73 / 150

11. Now, let's subtract the result from the previous step from the number -4 and 1: -4 - 73 / 150

To subtract a fraction from an integer, we need to have a common denominator:

-4 = -4 * 150 / 150 = -600 / 150

Now, perform the subtraction:

-600 / 150 - 73 / 150 = (-600 - 73) / 150 = -673 / 150

The simplified result is -673 / 150.
