Question

1/13 * (8 2/3 / 1 4/9 - 3 38 + 1 5/8)- 1 5/6= пж с действиями

Answer 1

1) 8 2/3  :  1 4/9 = 26/3  :  13/9 = 26/3  *  9/13 =  6
2)6  -  3 3/8 = 6  -  27/8  = 48/8  -  27/8 =  21/8 = 2 5/8
3) 2 5/8  +  1 5/8 = 21/8  +  13/8 = 34/8 = 17/4 = 4 1/4
4)1/13  *  4 1/4 = 1/13  *  17/4 =  17/52
5)17/52  -  1 5/6 = 17/52  -  11/6  = 51/156  -  286/156 =  - 235/156 = - 1 79/156
ОТВЕТ - 1 79/156

Answer 2

Calculating the Expression 1/13 * (8 + 2/3 + 1 + 4/9 - 3 + 38 + 1 + 5/8) - 1 + 5/6

To solve the given expression, let's break it down step by step.

1. First, let's calculate the value inside the parentheses. 2. Then, we'll multiply the result by 1/13. 3. After that, we'll subtract 1 from the result. 4. Finally, we'll add 5/6 to the result.

Calculating the Value Inside the Parentheses

The expression inside the parentheses is: 8 + 2/3 + 1 + 4/9 - 3 + 38 + 1 + 5/8

Step 1: Convert Mixed Numbers to Improper Fractions

- 2/3 can be written as 2/3 - 4/9 can be written as 4/9 - 5/8 can be written as 5/8

Step 2: Add the Numbers Inside the Parentheses

8 + 2/3 + 1 + 4/9 - 3 + 38 + 1 + 5/8 = 42 11/24

Calculating the Entire Expression

Now, let's calculate the entire expression: 1/13 * (42 11/24) - 1 + 5/6

Step 1: Multiply by 1/13

(42 11/24) * 1/13 = 3 8/13

Step 2: Subtract 1

3 8/13 - 1 = 2 8/13

Step 3: Add 5/6

2 8/13 + 5/6 = 3 71/78

The value of the given expression 1/13 * (8 + 2/3 + 1 + 4/9 - 3 + 38 + 1 + 5/8) - 1 + 5/6 is 3 71/78.
