Question

(15,5:0,25-0,08*200):2,3-1,3

Answer 1

Ответ:

18,7

Пошаговое объяснение:

1) 15.5 : 0,25 =62

2) 0,08 * 200 = 16

3) 62 - 16 = 46

4) 46 : 2.3 = 20

5) 20 - 1.3 = 18.7

Answer 2

Let's break down the given expression and solve it step by step according to the order of operations (PEMDAS):

1. First, we need to perform the multiplication inside the parentheses:

15,5:0,25 - 0,08 * 200 = 15,5:0,25 - 16

2. Then, we need to perform the division:

15,5:0,25 - 16 = 62 - 16

3. Next, we need to perform the subtraction:

62 - 16 = 46

4. Finally, we need to perform the subtraction outside the parentheses:

46 / 2,3 - 1,3 = 20 - 1,3

5. And the last step is to perform the subtraction:

20 - 1,3 = 18,7

Therefore, the final answer is 18,7.
