2/9+5/12
Дроби срочно

Answer 1

Пошаговое объяснение:

$\frac{5}{8} - \frac{3}{10} = \frac{25 - 12}{40} = \frac{13}{40}$

$\frac{2}{7} + \frac{1}{3} = \frac{6 + 7}{21} = \frac{13}{21}$

$\frac{2}{15} + \frac{3}{20} = \frac{8 + 9}{60} = \frac{17}{60}$

$\frac{2}{9} + \frac{5}{12} = \frac{8 + 15}{36} = \frac{23}{36}$
