Ответ:

\[1\frac{17}{27}=\frac{44}{27},\qquad 4\frac{4}{9}=\frac{40}{9}.\]

\[\frac{44}{27}:\frac{22}{45}=\frac{44}{27}\cdot\frac{45}{22}=\frac{10}{3}.\]

\[10-\frac{10}{3}=\frac{20}{3}.\]

\[\frac{20}{3}:\frac{40}{9}=\frac{20}{3}\cdot\frac{9}{40}=\frac{3}{2}=1\frac{1}{2}.\]

Ответ: \(1\frac{1}{2}\).
