-1.1
1.1
5.7
-5.7

Explanation:

Step1: Identify the operation

We need to calculate the sum of -3.4 and 2.3.

Step2: Perform the addition

When adding a negative number and a positive number, we can think of it as subtracting the absolute value of the negative number's magnitude from the positive number's magnitude if the positive number has a smaller absolute value. So, $-3.4 + 2.3 = -(3.4 - 2.3)$

Step3: Calculate the difference inside the parentheses

$3.4 - 2.3 = 1.1$

Step4: Apply the negative sign

So, $-(3.4 - 2.3) = -1.1$

Answer:

-1.1 (corresponding to the option: -1.1)
