Question

-2.1+4.7+(-3.8)+2.1+(-7.3)+4.9+(-2.8)

Answer 1

Ответ:

-4,3

Пошаговое объяснение:

-2.1+4.7+(-3.8)+2.1+(-7.3)+4.9+(-2.8) = -2.1 + 4.7 - 3.8 + 2.1 -7.3 + 4.9 -2.8 = -4,3

Answer 2

Let's calculate the expression:

-2.1 + 4.7 + (-3.8) + 2.1 + (-7.3) + 4.9 + (-2.8)

To simplify, we'll combine like terms:

(-2.1 + 2.1) + (4.7 - 3.8) + (-7.3 + 4.9 - 2.8)

Now, evaluate the expressions in each parenthesis:

0 + 0.9 + (-4.9)

Finally, add the remaining terms:

0.9 - 4.9 = -4

So, the final result is -4.
