Answer 1

Ответ:

Пошаговое объяснение:

1)

24 : (-8/11) = 24 * (-11/8) = 3 * (-11/1) =

-33/1 = -33

2)

81/11 : (-9) = 81/11 * (-1/9) = 9/11 * (-1/1) = -9/11

3)

-1. 2/7 : (-10. 1/7) = -9/7 : (-71/7) =

-9/7 * (-7/71) = 9/71

Answer 2

Ответ:

24:(-8/11)=24/1•(-11/8)=-33

81/11:(-9)=81/11•(-1/9)=-9/11

(-1 2/7):(-10 1/7)=9/7:71/7=9/7•7/71=9/71

Answer 3

1) To solve the expression 24:(-8/11), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we need to evaluate the expression inside the parentheses, which is -8/11. Dividing -8 by 11 gives us approximately -0.7273.

Next, we can substitute this value back into the original expression: 24 / (-0.7273). Dividing 24 by -0.7273 gives us approximately -33.

Therefore, the value of 24:(-8/11) is approximately -33.

2) To solve the expression 81/11:(-9), we again need to follow the order of operations.

First, we need to evaluate the expression inside the parentheses, which is -9.

Next, we can substitute this value back into the original expression: 81/11 / (-9). Dividing 81/11 gives us approximately 7.3636.

Dividing 7.3636 by -9 gives us approximately -0.8182.

Therefore, the value of 81/11:(-9) is approximately -0.8182.

3) To solve the expression (-1+2/7):(-10+1/7), we again need to follow the order of operations.

First, we need to evaluate the expressions inside the parentheses.

-1 + 2/7 gives us approximately -0.7143.

-10 + 1/7 gives us approximately -9.8571.

Next, we can substitute these values back into the original expression: -0.7143 / -9.8571. Dividing -0.7143 by -9.8571 gives us approximately 0.0725.

Therefore, the value of (-1+2/7):(-10+1/7) is approximately 0.0725.

I hope this helps! Let me know if you have any further questions.
