2 + 3 + 5 +  \frac{5}{7}  =  \frac{75}{7}

6000 \div  \frac{75}{7}  = 560

560 \times 2 = 1120

560 \times 3 = 1680

560 \times 5 = 2800

560 \times  \frac{5}{7}  = 400

Ответ : 1120,1680,2800,400.

Пошаговое объяснение:

1 число = 2х

2 число = 3х

3 число = 5х

4 число = 5/7х

2х + 3х + 5х + 5/7х = 6000

10х + 5/7х = 6000

10. 5/7х = 6000

75/7х = 6000

х = 6000 : 75/7

х = 6000 * 7/75

х = 80 * 7/1

х = 560/1

х = 560

1 число = (2х) = 2 * 560 = 1120

2 число = (3х) = 3 * 560 = 1680

3 число = (5х) = 5 * 560 = 2800

4 число = (5/7х) = 5/7 * 560 = 5/1 * 80 = 400/1 = 400

1120 + 1680 + 2800 + 400 = 6000
