Answer 1

Пошаговое объяснение:

$1) \frac{3}{20} + \frac{2}{15} = \frac{9 + 8}{60} = \frac{17}{60} \\ 2) \frac{17}{32} - \frac{5}{12} = \frac{51 - 40}{96} = \frac{11}{96} \\ 3) \frac{11}{28} + \frac{9}{14} = \frac{11 + 18}{28} = \frac{29}{28} = 1 \frac{1}{28} \\ 4) \frac{35}{36} - \frac{41}{45} = \frac{175 - 164}{180} = \frac{11}{180} \\ 5)3 \frac{21}{25} + 1 \frac{2}{5} = 4 \frac{21 + 10}{25} = 4 \frac{31}{25} = 5 \frac{6}{25} \\ 6)4 \frac{13}{16} - 2 \frac{3}{8} = 2 \frac{13 - 6}{16} = 2 \frac{7}{16} \\ 7)5 \frac{5}{6} - \frac{31}{48} = 5 \frac{40 - 31}{48} = 5 \frac{9}{48} = 5 \frac{3}{16} \\ 8)6 \frac{4}{7} - 2 \frac{37}{77} = 4 \frac{44 - 37}{77} = 4 \frac{7}{77} = 4 \frac{1}{11}$
