Question

1 1/20* (-8/21)+7/72:(-5/36)решите срочно​

Answer 1

21/20×-8/21 + 7/72×-36/5

-8/20 - 7/10

-4/10 - 7/10 то есть - 0,4 - 0,7

-11/10 то есть -1,1

Answer 2

To solve the expression 1 + 1/20 * (-8/21) + 7/72 : (-5/36), we can follow the order of operations (PEMDAS/BODMAS).

Step 1: Simplify the multiplication and division within the expression.

- Multiply 1/20 by -8/21: (1/20) * (-8/21) = -8/420 = -2/105 - Divide 7/72 by -5/36: (7/72) : (-5/36) = (7/72) * (-36/5) = -252/360 = -7/10

Step 2: Add and subtract the simplified values.

- Add 1 and -2/105: 1 + (-2/105) = 105/105 + (-2/105) = 103/105 - Divide the result by -7/10: (103/105) : (-7/10) = (103/105) * (-10/7) = -1030/735 = -206/147

Therefore, the solution to the expression 1 + 1/20 * (-8/21) + 7/72 : (-5/36) is -206/147.

Please note that the above solution is based on the given expression and the order of operations. If there are any additional requirements or constraints, please let me know.
