Ответ:

Пошаговое объяснение:

$(\frac{2}{9} +(-\frac{5}{9} )+\frac{2}{3} =\frac{1}{3} \\\\1)\frac{2}{9} +(-\frac{5}{9} )=\frac{2}{9} -\frac{5}{9} =-\frac{3}{9} =-\frac{1}{3} \\\\2)-\frac{1}{3} +\frac{2}{3} =\frac{1}{3}$

Answer 3

To solve this expression, first perform the arithmetic operations within the parentheses and then add the result to the fraction outside the parentheses.

Given expression: (2/9 + (-5/9)) + 2/3

Step 1: Calculate the sum within the parentheses: (2/9 + (-5/9)) = (2/9 - 5/9) = -3/9

Step 2: Add the result from Step 1 to the fraction outside the parentheses: (-3/9) + 2/3

Now, let's find a common denominator for the fractions within the expression, which is 9:

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

So, the final result of the expression is 1/3.
