Answer 2

Let's solve each expression step by step:

1. -2 + 1.3 / 4: -2 + (1.3 / 4) = -2 + 0.325 = -1.675

2. 3 + (1. - 2 / 7): 3 + (1. - 0.2857) = 3 + 0.7143 = 3.7143

3. 2.2 / 3 + (-1.5 / 6): (2.2 / 3) + (-0.25) = 0.7333 - 0.25 = 0.4833

4. -5.1 / 3 + 4,5: (-5.1 / 3) + 4.5 = -1.7 + 4.5 = 2.8

Note that in the fourth expression, you've used a comma (,) instead of a period (.) to separate the integer part from the fractional part. The correct representation would be "4.5."

So the results of the expressions are:

1. -2 + 1.3 / 4 = -1.675
2. 3 + (1. - 2 / 7) = 3.7143
3. 2.2 / 3 + (-1.5 / 6) = 0.4833
4. -5.1 / 3 + 4.5 = 2.8
