Question

Вычислите значения выражения 5 1/7 : b, если b = 12 ;48; 9/14; 18/21

Answer 1

Ответ:

$5 \frac{1}{7} = \frac{36}{7}$

1. При b = 12

$\frac{36}{7} : 12 = \frac{36}{7} * \frac{1}{12} =\frac{3}{7}$

2. При b = 48

$\frac{36}{7} : 48 = \frac{36}{7} * \frac{1}{48} =\frac{3}{28}$

3. При b = 9/14

$\frac{36}{7} : \frac{9}{14} = \frac{36}{7} * \frac{14}{9} =\frac{56}{7} = 8$

4. При b = 18/21

$\frac{36}{7} : \frac{18}{21} = \frac{36}{7} * \frac{21}{18} = 6$
