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
Wrong
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.
Wrongly
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.
To add −815 and 415, we need to find the sum of these two numbers.
-815 + 415 = -400
So the correct answer is:
-400
To add fractions and decimals, you need to follow these steps:

3. Add the numerators together and keep the denominator the same.
-815 + 415 = -400
4. Write the result as a fraction or decimal, depending on the desired format.
-400 can be written as a fraction with a denominator of 1: -400/1
Therefore, the correct response is: -400
