Answer 1

удачи там я под черерточкой написала два варианта ответа ! запиши один так как вы записываете в школе !!!

Answer 2

$\frac{7}{3} \times ( - \frac{13}{2} ) \times \frac{2}{5} ( - \frac{6}{7} ) \\ 13 \times \frac{1}{5} \times 2 \\ \frac{26}{5} \\ 5.2$

Answer 3

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression can be simplified as follows:

7/3 * (-6.5) * 0.4 * (-1 6/7)

Step 1: Deal with the mixed number: -1 6/7 can be written as -1 + 6/7 = -1 + 6/7 = -7/7 + 6/7 = -1 + 6/7

Step 2: Now rewrite the expression with the mixed number: 7/3 * (-6.5) * 0.4 * (-1 + 6/7)

Step 3: Distribute the multiplication: (7/3) * (-6.5) * 0.4 * -1 + (7/3) * (-6.5) * 0.4 * (6/7)

Step 4: Perform the calculations: (7/3) * (-6.5) * 0.4 * -1 = -91/15 ≈ -6.067

(7/3) * (-6.5) * 0.4 * (6/7) = -49/15 ≈ -3.267

Step 5: Add the results together: -6.067 + (-3.267) ≈ -9.334

So, the simplified result of the expression is approximately -9.334.
