Пошаговое объяснение:

22,05 : 2,1 =10,5

20-10,5=9,5

9,5×6,4=60,8

60,8+9,2=70

Answer 2

To solve the expression (20 - 22.05 : 2.1) ∙ 6.4 + 9.2, let's break it down step by step:

First, let's perform the division: 22.05 ÷ 2.1 = 10.5.

Now the expression becomes (20 - 10.5) ∙ 6.4 + 9.2.

Next, subtract 10.5 from 20: 20 - 10.5 = 9.5.

The expression now becomes 9.5 ∙ 6.4 + 9.2.

Multiply 9.5 by 6.4: 9.5 ∙ 6.4 = 60.8.

Finally, add 60.8 and 9.2: 60.8 + 9.2 = 70.

Therefore, the result of the expression (20 - 22.05 : 2.1) ∙ 6.4 + 9.2 is 70.
