Question

20,8÷(12 - 11,36) - 8 : 12,5 + 4,7-5,2=​

Answer 1

Ответ:

To simplify the expression 20.8÷(12 - 11.36) - 8 ÷ 12.5 + 4.7 - 5.2, we can follow the order of operations (PEMDAS/BODMAS):

First, we need to simplify the parentheses:

12 - 11.36 = 0.64

Next, we perform the division:

20.8 ÷ 0.64 = 32.5

Then, we continue with the remaining operations:

32.5 - 8 ÷ 12.5 + 4.7 - 5.2

Now, we perform the division:

8 ÷ 12.5 = 0.64

Substituting the values:

32.5 - 0.64 + 4.7 - 5.2

Next, we perform the addition and subtraction from left to right:

32.5 - 0.64 = 31.86

31.86 + 4.7 = 36.56

36.56 - 5.2 = 31.36

Therefore, the simplified expression is 31.36.
