Answer 2

It seems like you have an expression that involves subtraction of fractions. Let's break down the expression step by step:

1. Start with the first subtraction: -(-2,2/3 - 1,2/3)

   The negative sign outside the parentheses will change the sign of each term inside the parentheses. So, the expression becomes: 2,2/3 - 1,2/3

2. Perform the subtraction of fractions: 2,2/3 - 1,2/3

   To subtract fractions, they need a common denominator. The common denominator here is 3. Convert both fractions to have the same denominator: 2,2/3 = 2 * 3/3 + 2/3 = 6/3 + 2/3 = 8/3 1,2/3 = 1 * 3/3 + 2/3 = 3/3 + 2/3 = 5/3

   Now subtract: 8/3 - 5/3 = 3/3 = 1

So, the result of the first part is 1.

Now, let's move on to the second subtraction:

3. The expression is: 3,2/7 - 1,2/7

   As before, let's find a common denominator, which is 7 in this case: 3,2/7 = 3 * 7/7 + 2/7 = 21/7 + 2/7 = 23/7 1,2/7 = 1 * 7/7 + 2/7 = 7/7 + 2/7 = 9/7

   Now subtract: 23/7 - 9/7 = 14/7 = 2

So, the result of the second part is 2.

Finally, let's subtract the two results: 1 - 2 = -1

Therefore, the overall result of the given expression is -1.
