Помогите пожалуйста и напишите дополнительный множитель

Answer 1

Ответ:

$\frac{4}{45} + \frac{11}{60} = \frac{16 + 33}{180} = \frac{49}{180}$

$\frac{11}{12} + \frac{9}{16} = \frac{44 + 27}{48} = \frac{71}{48}$

$\frac{13}{24} + \frac{2}{15} = \frac{65 + 16}{120} = \frac{81}{120} = \frac{27}{40}$

$\frac{5}{48} + \frac{5}{36} = \frac{15 + 20}{144} = \frac{35}{144}$

$\frac{7}{18} - \frac{7}{24} = \frac{28 - 21}{72} = \frac{7}{72}$

$\frac{11}{36} - \frac{7}{24} = \frac{22 - 21}{72} = \frac{1}{72}$

$\frac{1}{6} - \frac{1}{15} = \frac{5 - 2}{30} = \frac{3}{30} = \frac{1}{10}$

$\frac{5}{9} - \frac{5}{12} = \frac{20 - 15}{36} = \frac{5}{36}$
