Question

What is the sum of −4.5 + 3.7?(1 point) Responses 0.8 -0.8 -0.8 10.2 -10.2

Answer 1

To find the sum of -4.5 and 3.7, we can perform the addition:

\[
-4.5 + 3.7
\]

When adding a negative number and a positive number, we subtract the smaller absolute value from the larger absolute value and take the sign of the larger absolute value:

\[
3.7 - 4.5 = -0.8
\]

Therefore, the sum of -4.5 and 3.7 is:

\[
-0.8
\]

So the correct response is **-0.8**.
