Решение:
\[ 4 \frac{2}{3} = \frac{14}{3} \]
\[ 2 \frac{2}{15} = \frac{32}{15} \]
\[ 3,5 = \frac{35}{10} = \frac{7}{2} \]
\[ \frac{7}{2} + \frac{14}{3} + \frac{32}{15} \]
Приведем к общему знаменателю 30:
\[ \frac{7 \cdot 15}{30} + \frac{14 \cdot 10}{30} + \frac{32 \cdot 2}{30} = \frac{105 + 140 + 64}{30} = \frac{309}{30} = \frac{103}{10} = 10,3 \]
\[ 1 \frac{1}{20} = \frac{21}{20} \]
\[ 4,1 = \frac{41}{10} \]
\[ \frac{21}{20} + \frac{41}{10} = \frac{21}{20} + \frac{82}{20} = \frac{103}{20} = 5,15 \]
\[ \frac{10,3}{5,15} = 2 \]
