Answer 2

It seems like you've provided a mathematical expression that needs to be evaluated. Let's break down the expression step by step:

1. Start with the first set of parentheses: -(4, 75 - 6 8/9)
2. Convert the mixed number to an improper fraction: 75 - 6 8/9 = 75 - (6 * 9 + 8) / 9 = 75 - (54 + 8) / 9 = 75 - 62 / 9
3. Perform the subtraction: 75 - 62 / 9

Now, let's calculate the value of this expression:

75 - 62 / 9 = (75 * 9 - 62) / 9 = (675 - 62) / 9 = 613 / 9

So, the value of the first expression within the parentheses is 613 / 9.

Moving on to the second set of parentheses: (0,25 - 1 1/9)

1. Convert the mixed number to an improper fraction: 1 1/9 = (1 * 9 + 1) / 9 = 10 / 9
2. Perform the subtraction: 0,25 - 10 / 9

Now, let's calculate the value of this expression:

0,25 - 10 / 9 = (0.25 * 9 - 10) / 9 = (2.25 - 10) / 9 = -7.75 / 9

So, the value of the second expression within the parentheses is -7.75 / 9.

Finally, subtract the two results:

(613 / 9) - (-7.75 / 9) = (613 + 7.75) / 9 = 620.75 / 9

So, the final value of the entire expression is approximately 68.9722.

Please double-check your original expression and calculations to ensure accuracy.
