Answer 3

7/9 + (1 + 2/9 - 5/9) = 7/9 + (1 + (2/9 - 5/9)) First, we need to find the value of the expression inside the parentheses: 2/9 - 5/9 = -3/9 = -1/3 Now we can substitute this value back into the original expression: 7/9 + (1 - 1/3) To add the whole numbers and fractions, we need to find a common denominator, which in this case is 3: 7/9 + (3/3 - 1/3) = 7/9 + 2/3 Now we need to find a common denominator for 9 and 3, which is 9: (7*3)/(9*3) + (2*3)/(3*3) = 21/27 + 6/27 Now we can add the fractions together: 21/27 + 6/27 = 27/27 = 1 So the final answer is 1.
