Question

(-5) умножить на 2/3=7 умножить на ( -1 /2)=

Answer 1

Ответ:

$- 5 \times \frac{2}{5} = - (5 \times 4) = - 20$

7×(-1/2)=-(7×5)=-35

Answer 2

To calculate the expression (-5) multiplied by 2/3 and then multiplied by 7 and (-1/2), follow these steps:

1. First, compute the multiplication of (-5) and 2/3: (-5) * (2/3) = -10/3

2. Next, multiply the result from step 1 by 7: -10/3 * 7 = -70/3

3. Finally, multiply the result from step 2 by (-1/2): -70/3 * (-1/2) = 70/6

Now, the final result is 70/6 or 11.67 when expressed as a decimal.
