Answer 2

\(\frac{5}{6}+\frac{3}{4}< \frac{19}{11}\)

\(\frac{17}{12}-\frac{9}{8}< \frac{1}{3}\)

\(\frac{4}{9}\times\frac{6}{5}=\frac{8}{15}\)

\(\frac{15}{4}:\frac{3}{8}>8\)

Answer 3

\(\frac{5}{6}+\frac{3}{4}=\frac{19}{12}< \frac{19}{11}\) 

\(\frac{17}{12}-\frac{9}{8}=\frac{7}{24}< \frac{1}{3}=\frac{8}{24}\) 

\(\frac{4}{9}\cdot\frac{6}{5}=\frac{24}{45}=\frac{8}{15}\)

\(\frac{15}{4}:\frac{3}{8}=\frac{15}{4}\cdot\frac{8}{3}=\frac{5}{2}=2\frac{1}{2}< 8\)
