Add $81.76$ to $34.587$ and round your answer to the nearest tenth.
To add these two numbers, I need to align the decimal points and add the digits in each place value, starting from the rightmost ones. I get $81.76 + 34.587 = 116.347$. To round to the nearest tenth, I look at the hundredths digit, which is $4$. Since $4$ is less than $5$, I do not change the tenths digit and just drop the hundredths and thousandths digits. So the final answer is $116.3$.
