Which expression is equivalent to \( 6.1+8.6 \) ?

Did you know that \( 6.1 + 8.6 \) can be converted into a fraction for a different perspective? By rewriting \( 6.1 \) as \( \frac{61}{10} \) and \( 8.6 \) as \( \frac{86}{10} \), you can add them as \( \frac{61 + 86}{10} = \frac{147}{10} \) or simply \( 14.7 \) in decimal form! If you want to break it down, you could round \( 6.1 \) and \( 8.6 \) to \( 6 \) and \( 9 \), respectively, making it easier to estimate that \( 6 + 9 = 15 \). This helps you see that \( 14.7 \) is indeed very close to this rounded total, giving you a quick mental check on your addition!
