Question

1,26×0/27÷0,84-5/6 Надо решить

Answer 1

Ответ:

1. 1,26 * 10 / 27 = 126 / 100 * 10 / 27 = 14 / 10 * 1 / 3 = 14 / 30 = 7 / 15;

2. 7 / 15 / 0,84 = 7 / 15 / 84 / 100 = 7 / 15 * 100 / 84 = 1 / 3 * 20 / 12 = 20 / 36 = 5 / 9;

3. 5 / 9 - 5 / 6 = 10 / 18 - 15 / 18 = - 5 / 18;

4. Ответ: - 5 / 18.

Answer 2

To solve the given expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets (None in this case)
2. Exponents/Orders (None in this case)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's proceed step by step:

1. 1,26 × 0 = 0 (Anything multiplied by 0 is 0)
2. 0 ÷ 27 = 0 (Anything divided by 0 is undefined)
3. 0 ÷ 0,84 = 0 (0 divided by any non-zero number is 0)
4. 0 - 5/6 = 0 - 0.8333... ≈ -0.8333...

So, the result of the expression is approximately -0.8333.
