Решение:
\[ 3 \frac{2}{9} = \frac{3 \times 9 + 2}{9} = \frac{27 + 2}{9} = \frac{29}{9} \]
\[ 1 \frac{1}{4} = \frac{1 \times 4 + 1}{4} = \frac{4 + 1}{4} = \frac{5}{4} \]
\[ \frac{29}{9} = \frac{29 \times 4}{9 \times 4} = \frac{116}{36} \]
\[ \frac{5}{4} = \frac{5 \times 9}{4 \times 9} = \frac{45}{36} \]
\[ \frac{116}{36} - \frac{45}{36} = \frac{116 - 45}{36} = \frac{71}{36} \]
\[ \frac{71}{36} = 1 \frac{71 - 36}{36} = 1 \frac{35}{36} \]
Ответ: \( 1 \frac{35}{36} \)
