16. \( 1 \frac{7}{12}+4 \frac{9}{12} \)

To solve \( 1 \frac{7}{12}+4 \frac{9}{12} \), first, convert the mixed numbers into improper fractions. For \( 1 \frac{7}{12} \), that becomes \( \frac{12 \cdot 1 + 7}{12} = \frac{19}{12} \). For \( 4 \frac{9}{12} \), it becomes \( \frac{12 \cdot 4 + 9}{12} = \frac{57}{12} \). Now, add the fractions: \[ \frac{19}{12} + \frac{57}{12} = \frac{76}{12}. \] This simplifies to \( \frac{19}{3} \) or \( 6 \frac{1}{3} \). So, \( 1 \frac{7}{12}+4 \frac{9}{12} = 6 \frac{1}{3} \). Multiplying fractions sounds complicated, but it’s actually pretty manageable with a bit of practice! A common mistake is to forget to simplify or convert mixed numbers first. Always check your work to make sure you’re adding the whole numbers together before dealing with the fractions! Keep practicing, and you’ll be a pro in no time!
