Answer 2

Let's solve the expression step by step:

1. 2 * 2 = 4

2. 1/3 - 5 5/6:

To subtract a mixed number (5 5/6) from a fraction (1/3), we need to convert the mixed number to an improper fraction and then perform the subtraction.

5 5/6 = (6 * 5 + 5) / 6 = 35/6

1/3 - 35/6:

To subtract fractions, they must have the same denominator. The common denominator for 3 and 6 is 6.

1/3 = 2/6 (multiply both numerator and denominator by 2)

Now we can subtract:

2/6 - 35/6 = (2 - 35) / 6 = -33/6 = -11/2

So, 1/3 - 5 5/6 = -11/2

3. 1.4 - 2.9:

Subtracting decimals:

1.4 - 2.9 = -1.5

Now, we have:

4 - (-11/2) / (-1.5)

To simplify the expression further, we divide by a fraction by multiplying by its reciprocal:

4 - (-11/2) / (-1.5) = 4 + 2/3 * (-1/1.5)

Now, let's multiply the fractions:

2/3 * (-1/1.5) = -2/4 = -1/2

Finally, we can complete the expression:

4 + (-1/2) = 3.5

So, the result of the expression is 3.5.
