Explicație pas cu pas:

Introduci intregii in fractie, daca este cazul) si faci calculul

2/7 : 3/5 = 2/7 x 5/3 = 10/21

_________

10/3 : 10/9 = 10/3 x 9/10 = 9/3 = 3

__________

65/8 : 65/16 = 65/8 x 16/65 = 16/8 = 2

__________

1 : 22/7 = 1 x 7/22 = 7/22

Răspuns:

[tex]a)\frac{2}{7}:\frac{3}{5} =\frac{2}{7}*\frac{5}{3} =\frac{10}{21} \\\\b)3\frac{1}{3}:1 \frac{1}{9}=\frac{10}{3}:\frac{10}{9}=\frac{10}{3}*\frac{9}{10}=\frac{9}{3}=3\\\\c)\frac{65}{8}:4\frac{1}{16} =\frac{65}{8}:\frac{65}{16}=\frac{65}{8}*\frac{16}{65}=\frac{16}{8}=2\\\\d)1:3\frac{1}{7}=1:\frac{22}{7}=1*\frac{7}{22} =\frac{7}{22} \\[/tex]
