Answer 2

It seems like you want to perform some mathematical operations with the given numbers. Let's break it down step by step:

1. Start with the expression "4-1,2":

   • This appears to be a subtraction operation: 4 - 1.2 = 2.8

2. Next, we have "а= -3 1/3":

   • This represents a variable assignment, where "a" is assigned the value of -3 1/3. You can express this as a mixed number: -3 1/3 = -10/3 or -3.33 (rounded to two decimal places).

3. Finally, you provided "(- 2 2/9":

   • It's not clear what operation you want to perform with this number. If you want to subtract it from the value of "a," you would subtract it as follows:
     • -10/3 - (-2 2/9) = -10/3 + 2 2/9

Let's calculate the result of this subtraction:

First, convert -10/3 to a mixed number: -10/3 = -3 1/3.

Now, we can add -3 1/3 and 2 2/9:

-3 1/3 + 2 2/9 = (-10/3) + (20/9)

To add these fractions, we need a common denominator, which is 9:

-30/9 + 20/9 = -10/9

So, the result of the expression is -10/9, or approximately -1.11 (rounded to two decimal places).
