Ответ:

Пошаговое объяснение:

6ав-1 1/3ав+2 2/3ав+2/3ав=(6-1 1/3+2 2/3+2/3)*ав=(6-1 1/3+2 4/3)*ав=

(6+1 3/3)ав=(6+2)ав=8ав

Answer 2

To simplify the expression, let's break it down step by step:

1. Start with the given expression: 6ab + (-1 1/3 ab) - (-2 2/3 ab - 2/3 ab)

2. Simplify the mixed number -1 1/3 to an improper fraction: -1 1/3 = -4/3

3. Rewrite the expression using the improper fraction: 6ab + (-4/3)ab - (-2 2/3 ab - 2/3 ab)

4. Simplify the subtraction of the fractions: -(-2 2/3 ab - 2/3 ab) becomes -(-4/3 ab) = 4/3 ab

5. Now, substitute the simplified expression back into the original expression: 6ab + (-4/3)ab + 4/3 ab

6. Combine like terms: 6ab + (-4/3)ab + 4/3 ab = (6 - 4/3 + 4/3)ab

7. Simplify the coefficient: 6 - 4/3 + 4/3 = 6 - (4/3 - 4/3) = 6

8. The final simplified expression is: 6ab
