Answer 1

Ответ:

-2,1

Пошаговое объяснение:

1.-6,7+4,8= -1,9

2.-1,9-5,3= -7,2

3.-7,2-7,7= -14,9

4.-14,9+12,8= -2,1

Answer 2

To calculate the expression, simply add up the numbers:

-6.7 + (+4.8) + (-5.3) + (-7.7) + (+12.8)

First, let's remove the unnecessary positive signs:

-6.7 + 4.8 - 5.3 - 7.7 + 12.8

Next, add the numbers together:

(-6.7 + 4.8) - 5.3 - 7.7 + 12.8

(-1.9) - 5.3 - 7.7 + 12.8

-1.9 - 5.3 - 7.7 + 12.8

-7.2 - 7.7 + 12.8

-14.9 + 12.8

-2.1

Therefore, the result of the expression -6.7 + (+4.8) + (-5.3) + (-7.7) + (+12.8) is -2.1.
