Answer 1

ответ

А) (0,79-0,206)+(6,7-4,2305)=3,0535

Б) (20,6-7,987)-2,503=10,11

Answer 2

To solve the given expressions:

A) (0.79 - 0.206) + (6.7 - 4.2305)

In this expression, you need to perform addition and subtraction operations from left to right:

0.79 - 0.206 = 0.584 6.7 - 4.2305 = 2.4695

Now, you can add the results together:

0.584 + 2.4695 = 3.0535

Therefore, the value of expression A is 3.0535.

B) (20.6 - 7.987) - 2.503

Similarly, you need to perform subtraction operations first:

20.6 - 7.987 = 12.613 Now, subtract 2.503 from the previous result:

12.613 - 2.503 = 10.11

Therefore, the value of expression B is 10.11.
