Question

5/7•(-2,6)•0,6•(-2 1/3). -8/9•(-5/29)•9/16•(-58) решите пошагово

Answer 1

Ответ:

Пошаговое объяснение:

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

2)-13/7*3/5=-39/35

3)-39/35*(-7/3)=13/5

-8/9*-(5/29)=40/261

40/261*9/16=45/58

45/58*(-58)=-5

Answer 2

To solve this expression step-by-step, we'll perform the calculations in the given order:

Step 1: Calculate 5/7 • (-2,6) Step 2: Calculate the result from Step 1 • 0,6 Step 3: Calculate the result from Step 2 • (-2 1/3) Step 4: Calculate -8/9 • (-5/29) Step 5: Calculate the result from Step 4 • 9/16 Step 6: Calculate the result from Step 5 • (-58)

Let's begin:

Step 1: Calculate 5/7 • (-2.6) This step involves multiplying 5/7 by -2.6: (5/7) • (-2.6) = -1 * (5/7) * (26/10) = -1 * (5/7) * (13/5) = -65/35

Step 2: Calculate the result from Step 1 • 0.6 This step involves multiplying the result from Step 1 by 0.6: (-65/35) • 0.6 = -65/35 * 6/10 = -65/35 * 3/5 = -195/175

Step 3: Calculate the result from Step 2 • (-2 1/3) This step involves multiplying the result from Step 2 by (-2 1/3): To do this, we need to convert (-2 1/3) to an improper fraction: (-2 1/3) = -2 + 1/3 = (-2 * 3 + 1) / 3 = -7/3

Now, we multiply the result from Step 2 by (-7/3): (-195/175) • (-7/3) = -195/175 * -7/3 = 1365/525

Step 4: Calculate -8/9 • (-5/29) This step involves multiplying -8/9 by -5/29: (-8/9) • (-5/29) = 40/261

Step 5: Calculate the result from Step 4 • 9/16 This step involves multiplying the result from Step 4 by 9/16: (40/261) • (9/16) = 360/4176

Step 6: Calculate the result from Step 5 • (-58) This step involves multiplying the result from Step 5 by (-58): (360/4176) • (-58) = -360 * 58 / 4176 = -20/29

The final result is -20/29.
