Question

(1,25 - 1. 1/3 ) * (-5. 1/7) + 1. 1/6 : 5 4/9= помогите пж пж

Answer 1

Ответ:

1,25 - 1. 1/3=1 3/12 - 1 4/12= -1/12

-1/12 * (-5 1/7)= 1/12 * 36/7= 3/7

1 1/6 : 5 4/9= 7/6 * 9/49= 3/7

3/7+3/7= 6/7

Answer 2

To solve the given equation (1.25 - 1 + 1/3) * (-5 + 1/7) + 1 + 1/6 = 5 + 4/9, we can follow the order of operations (also known as PEMDAS or BODMAS) to simplify the expression step by step.

Step 1: Simplify the expressions within parentheses

(1.25 - 1 + 1/3) * (-5 + 1/7) + 1 + 1/6 = (0.25 + 1/3) * (-5 + 1/7) + 1 + 1/6

Step 2: Perform addition and subtraction within parentheses

(0.25 + 1/3) * (-5 + 1/7) + 1 + 1/6 = (0.25 + 1/3) * (-35/7 + 1/7) + 1 + 1/6

Step 3: Simplify the expressions within parentheses

(0.25 + 1/3) * (-35/7 + 1/7) + 1 + 1/6 = (0.25 + 1/3) * (-34/7) + 1 + 1/6

Step 4: Perform multiplication

(0.25 + 1/3) * (-34/7) + 1 + 1/6 = (3/12 + 4/12) * (-34/7) + 1 + 1/6

Step 5: Simplify the expressions within parentheses

(3/12 + 4/12) * (-34/7) + 1 + 1/6 = (7/12) * (-34/7) + 1 + 1/6

Step 6: Perform multiplication

(7/12) * (-34/7) + 1 + 1/6 = -34/12 + 1 + 1/6

Step 7: Simplify the expression

-34/12 + 1 + 1/6 = -17/6 + 1 + 1/6

Step 8: Perform addition

-17/6 + 1 + 1/6 = -17/6 + 6/6 + 1/6

Step 9: Simplify the expression

-17/6 + 6/6 + 1/6 = -10/6 + 1/6

Step 10: Perform addition

-10/6 + 1/6 = -9/6

Step 11: Simplify the expression

-9/6 = -3/2

Therefore, the solution to the equation (1.25 - 1 + 1/3) * (-5 + 1/7) + 1 + 1/6 = 5 + 4/9 is -3/2.
