Question

Помогите плиз!!!
записано должно быть таким:
6/35+3/10=12/70+21/70=33/70

Answer 1

Ответ:

Пошаговое объяснение:

2/7 - 5/42 = 12/42 - 5/42 = 7/42 = 1/6

1/11 + 1/33 = 3/33 + 1/33 = 4/33

5/12 + 5/18 = 15/36 + 10/36 = 25/36

4/35 + 1/28 = 16/140 + 5/140 = 21/140 = 3/20

19/20 - 3/8 - 1/5 = 38/40 - 15/40 - 8/40 = 15/40 = 3/8

Answer 2

Ответ ;

$\frac{2}{7} - \frac{5}{42} = \frac{12}{42} - \frac{5}{42} = \frac{7}{42}$

$\frac{1}{11} + \frac{1}{33} = \frac{3}{33} + \frac{1}{33} = \frac{4}{33}$

$\frac{5}{12} + \frac{5}{18} = \frac{15}{36} + \frac{10}{36} = \frac{25}{36}$

$\frac{4}{35} + \frac{ 1}{28} = \frac{16}{140} + \frac{5}{140} = \frac{21}{140}$

$\frac{19}{20} - \frac{3}{8} - \frac{1}{5} = \frac{38}{40} - \frac{15}{40} - \frac{8}{40} = \frac{15}{40}$
