Чтобы сложить две дроби с разными знаменателями, их надо привести к общему знаменателю, а затем применить правило сложения дробей с общим знаменателем.

Привет! Давай разберем примеры на сложение дробей. Если знаменатели разные, мы приводим их к общему, а затем складываем числители. ### Первый столбик: 1. $\frac{32}{55} + \frac{23}{55} = \frac{55}{55} = 1$ 2. $\frac{5}{33} + \frac{6}{33} = \frac{11}{33} = \frac{1}{3}$ 3. $\frac{12}{48} + \frac{12}{48} = \frac{24}{48} = \frac{1}{2}$ 4. $\frac{1}{2} + \frac{1}{3} = \frac{3}{6} + \frac{2}{6} = \frac{5}{6}$ 5. $\frac{1}{3} + \frac{1}{4} = \frac{4}{12} + \frac{3}{12} = \frac{7}{12}$ 6. $\frac{1}{3} + \frac{1}{6} = \frac{2}{6} + \frac{1}{6} = \frac{3}{6} = \frac{1}{2}$ 7. $\frac{1}{10} + \frac{7}{100} = \frac{10}{100} + \frac{7}{100} = \frac{17}{100}$ 8. $\frac{3}{5} + \frac{9}{10} = \frac{6}{10} + \frac{9}{10} = \frac{15}{10} = 1\frac{5}{10} = 1\frac{1}{2}$ 9. $\frac{2}{3} + \frac{5}{6} = \frac{4}{6} + \frac{5}{6} = \frac{9}{6} = 1\frac{3}{6} = 1\frac{1}{2}$ 10. $\frac{15}{24} + \frac{3}{8} = \frac{15}{24} + \frac{9}{24} = \frac{24}{24} = 1$ 11. $\frac{7}{6} + \frac{16}{18} = \frac{21}{18} + \frac{16}{18} = \frac{37}{18} = 2\frac{1}{18}$ 12. $\frac{1}{12} + \frac{1}{6} = \frac{1}{12} + \frac{2}{12} = \frac{3}{12} = \frac{1}{4}$ 13. $\frac{1}{4} + \frac{1}{8} = \frac{2}{8} + \frac{1}{8} = \frac{3}{8}$ ### Второй столбик: 1. $\frac{1}{2} + \frac{3}{10} = \frac{5}{10} + \frac{3}{10} = \frac{8}{10} = \frac{4}{5}$ 2. $\frac{3}{36} + \frac{7}{9} = \frac{3}{36} + \frac{28}{36} = \frac{31}{36}$ 3. $\frac{2}{5} + \frac{3}{20} = \frac{8}{20} + \frac{3}{20} = \frac{11}{20}$ 4. $\frac{1}{6} + \frac{5}{12} = \frac{2}{12} + \frac{5}{12} = \frac{7}{12}$ 5. $\frac{11}{49} + \frac{6}{7} = \frac{11}{49} + \frac{42}{49} = \frac{53}{49} = 1\frac{4}{49}$ 6. $\frac{13}{24} + \frac{5}{8} = \frac{13}{24} + \frac{15}{24} = \frac{28}{24} = 1\frac{4}{24} = 1\frac{1}{6}$ 7. $\frac{3}{8} + \frac{6}{32} = \frac{12}{32} + \frac{6}{32} = \frac{18}{32} = \frac{9}{16}$ 8. $\frac{6}{120} + \frac{3}{20} = \frac{6}{120} + \frac{18}{120} = \frac{24}{120} = \frac{1}{5}$ 9. $\frac{9}{16} + \frac{50}{100} = \frac{9}{16} + \frac{1}{2} = \frac{9}{16} + \frac{8}{16} = \frac{17}{16} = 1\frac{1}{16}$ 10. $\frac{1}{6} + \frac{1}{9} = \frac{3}{18} + \frac{2}{18} = \frac{5}{18}$ 11. $\frac{2}{9} + \frac{5}{6} = \frac{4}{18} + \frac{15}{18} = \frac{19}{18} = 1\frac{1}{18}$ 12. $\frac{2}{9} + \frac{3}{8} = \frac{16}{72} + \frac{27}{72} = \frac{43}{72}$ 13. $\frac{2}{10} + \frac{6}{15} = \frac{6}{30} + \frac{12}{30} = \frac{18}{30} = \frac{3}{5}$ 14. $\frac{3}{10} + \frac{2}{12} = \frac{18}{60} + \frac{10}{60} = \frac{28}{60} = \frac{7}{15}$ 15. $\frac{5}{12} + \frac{4}{15} = \frac{25}{60} + \frac{16}{60} = \frac{41}{60}$ 16. $\frac{3}{4} + \frac{5}{18} = \frac{27}{36} + \frac{10}{36} = \frac{37}{36} = 1\frac{1}{36}$
