4 Schreibe als unechten Bruch. Beispiel: \( 3 \frac{5}{6}=3+\frac{5}{6}=\frac{18}{6}+\frac{5}{6}=\frac{23}{6} \) \( \begin{array}{llll}\text { a) } 1 \frac{3}{4} & \text { b) } 4 \frac{1}{5} & \text { c) } 2 \frac{1}{2} & \text { d) } 5 \frac{2}{3} \\ \text { e) } 10 \frac{1}{6} & \text { f) } 3 \frac{1}{10} & \text { g) } 3 \frac{1}{8} & \text { h) } 5 \frac{6}{7} \\ \text { i) } 9 \frac{5}{6} & \text { j) } 6 \frac{5}{9} & \text { k) } 8 \frac{2}{3} & \text { l) } 7 \frac{4}{11}\end{array} \)

a) \( 1 \frac{3}{4} = 1 + \frac{3}{4} = \frac{4}{4} + \frac{3}{4} = \frac{7}{4} \) b) \( 4 \frac{1}{5} = 4 + \frac{1}{5} = \frac{20}{5} + \frac{1}{5} = \frac{21}{5} \) c) \( 2 \frac{1}{2} = 2 + \frac{1}{2} = \frac{4}{2} + \frac{1}{2} = \frac{5}{2} \) d) \( 5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{15}{3} + \frac{2}{3} = \frac{17}{3} \) e) \( 10 \frac{1}{6} = 10 + \frac{1}{6} = \frac{60}{6} + \frac{1}{6} = \frac{61}{6} \) f) \( 3 \frac{1}{10} = 3 + \frac{1}{10} = \frac{30}{10} + \frac{1}{10} = \frac{31}{10} \) g) \( 3 \frac{1}{8} = 3 + \frac{1}{8} = \frac{24}{8} + \frac{1}{8} = \frac{25}{8} \) h) \( 5 \frac{6}{7} = 5 + \frac{6}{7} = \frac{35}{7} + \frac{6}{7} = \frac{41}{7} \) i) \( 9 \frac{5}{6} = 9 + \frac{5}{6} = \frac{54}{6} + \frac{5}{6} = \frac{59}{6} \) j) \( 6 \frac{5}{9} = 6 + \frac{5}{9} = \frac{54}{9} + \frac{5}{9} = \frac{59}{9} \) k) \( 8 \frac{2}{3} = 8 + \frac{2}{3} = \frac{24}{3} + \frac{2}{3} = \frac{26}{3} \) l) \( 7 \frac{4}{11} = 7 + \frac{4}{11} = \frac{77}{11} + \frac{4}{11} = \frac{81}{11} \)
