To solve the problem \( -8.15 + 4.15 \):
-
Align the numbers vertically: \[ -8.15
- 4.15 \]
-
Perform the addition:
- Start with the decimal parts: \( -0.15 + 0.15 = 0 \)
- Then add the whole numbers: \( -8 + 4 = -4 \)
So, \( -8.15 + 4.15 = -4.00 \).
The answer is: \[ \text{−4.00 (or simply −4)} \]
Based on the provided options, none of them match this result exactly, but if we are doing a quick check for the closest representation in a more typical fraction form from the result, you could consider rounding it or finding the nearest counterpart.
However, let’s analyze the options given:
- \( -415 \) (not a valid choice)
- \( -\frac{12}{15} \) (not relevant here)
- \( \frac{4}{5} \) (not relevant since we have a negative result)
- \( 415 \) (not a valid choice as well)
The correct answer \( -4 \) does not appear among the given choices, which suggests there may have been an oversight in the choices provided. Please check if there are more choices to choose from or if there are any modifications to these figures.
