Пошаговое объяснение:

1)5/7*(-2.6)= - 13/7

2)-13/7*0.6= - 39/35

3)- 39/35*-2 1/3=13/5=2 3/5

Answer 2

To solve the expression, let's perform the calculations step by step:

1. Start with the given expression: 5/7 • (-2.6) • 0.6 • (-2 1/3)

2. Begin by simplifying the mixed fraction (-2 1/3): -2 1/3 = -2 - 1/3 = -2 - (1/3) = -2 - 0.333... (approximately) ≈ -2.333...

3. Now, we can proceed with the multiplication: 5/7 • (-2.6) • 0.6 • (-2.333...)

4. Perform the multiplication: (5/7) * (-2.6) * 0.6 * (-2.333...) ≈ -0.857142857 * (-2.333...)

5. Calculate the final result: ≈ 2 (rounded to two decimal places)

Therefore, the approximate solution to the expression is 2. Please note that the result is rounded to two decimal places.
