Answer 1

Пошаговое объяснение:

$1) \: \frac{17}{24} \: \: \frac{26}{43} \: \: \frac{11}{9} \\ \\ 1) \: \: \frac{31}{72} \: \: \frac{8}{35} \: \:$

$2) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \frac{8 \times 13}{8 \times 15} = \frac{13}{15 } \\ \\ \frac{24}{16} = \frac{3}{2} \\ \\ \frac{1400}{420000} = \frac{14}{420} = \frac{1}{30} \\ \\ \frac{23 \times 5 + 5 \times 8}{35} = \frac{31}{7}$

$2). \\ \frac{23 \times 4}{23 \times 7} = \frac{4}{7} \\ \\ \frac{36}{45} = \frac{4}{5} \\ \\ \frac{1250}{10000} = \frac{125}{1000} = \frac{5}{40} = \frac{1}{8} \\ \\ \frac{15 \times 17 - 15 \times 9}{32} = \frac{120}{32} = \frac{15}{4}$
