Объяснение:

$frac{3,5 + 4frac{2}{3} + 2frac{2}{15}}{1frac{1}{20}+4,1} = frac{3frac{1}{2} + 4frac{2}{3} + 2frac{2}{15}}{1frac{1}{20}+4frac{1}{10}} = frac{frac{7}{2}+frac{14}{3} + frac{32}{15}}{frac{21}{20}+frac{41}{10}} = frac{frac{7cdot15+14cdot 10 + 32cdot2}{30}}{frac{21+41cdot2}{20}} = frac{frac{105+140+64}{30}}{frac{21+82}{20}} = frac{frac{309}{30}}{frac{103}{20}} = \\frac{309cdot20}{30cdot103} = frac{3cdot20}{30} = frac{60}{30} = 2$
