Answer 2

Let's simplify the expression step by step:

1. Start with multiplication and division from left to right: -5/6 × 3 = -5/2 (You can multiply numerators and denominators separately: -5/6 × 3/1 = -5/2) -1.8 ÷ -0.3 = 6 (You can divide -1.8 by -0.3 to get 6)

2. Now, we have: -5/2 + 2 - (-4)

3. Deal with the subtraction (which is the same as adding a negative number): -5/2 + 2 + 4

4. Convert the mixed number -5/2 to an improper fraction: -5/2 = -2 1/2

5. Add the fractions together with the whole number: -2 1/2 + 2 + 4

6. Convert the whole number 2 to a fraction with the same denominator as -1/2: 2 = 4/2

7. Add the fractions: -2 1/2 + 4/2 + 4

8. Combine the whole numbers and fractions: (-2 + 4) 1/2 + 4

9. Simplify further: 2 1/2 + 4

10. Finally, add the whole numbers and the fractions: 2 + 1/2 + 4 = 6 1/2

So, the simplified value of the expression is 6 1/2 or 6.5.
