To solve \( 1015 - 515 \):
First, we subtract the numbers:
\[ 1015 - 515 = 500 \]
Now, we look for a simplified form among the responses given:
- 1515
- Start Fraction 15 over 15 End Fraction (which equals 1)
- 13 (which is just 13)
- Start Fraction 1 over 3 End Fraction (which equals approximately 0.33)
- 515
None of these options represent the simplified result \( 500 \).
Please check the question or the options again, as none of the provided responses match the answer to the calculation \( 1015 - 515 = 500 \).
