Answer 1

To add fractions, we need to have a common denominator. In this case, the least common denominator is 15.

So, we have:

−815 = -48/15

415 = 4/15

Now, we can add them:

-48/15 + 4/15 = -44/15

Therefore, the correct answer is:

−44/15

Answer 2

Wrong

Answer 3

I apologize for the incorrect response. Let's try again.

To add −815 and 415, we simply add the numbers:

−815 + 415 = -400

Therefore, the correct answer is −400.

Answer 4

Wrongly

Answer 5

Apologies for the confusion. Let's solve the addition correctly this time.

To add -815 and 415, we can line up the numbers like this:

-815
+ 415
-------

To add the numbers, we start with the rightmost column:

5 + 5 = 10. Write down the 0 and carry over the 1.

1 + 1 + 1 = 3.

Now, put the 3 below the line:

-815
+ 415
-------
200

Therefore, the correct answer is 200.
