Accepted Answer

16) $3\frac{4}{7}+1\frac{8}{11}=4+\frac{4}{7}+\frac{8}{11}=4+\frac{44}{77}+\frac{56}{77}=4\frac{100}{77}=5\frac{23}{77}$.

Ответ: $5\frac{23}{77}$.

17) $\frac{7}{9}+8\frac{13}{27}=8+\frac{21}{27}+\frac{13}{27}=8+\frac{34}{27}=9\frac{7}{27}$.

Ответ: $9\frac{7}{27}$.

16) \(3\frac{4}{7}+1\frac{8}{11}\); 17) \(\frac{7}{9}+8\frac{13}{27}\)
