01)

$\frac{10}{25}.\frac{10}{x} \\10x=25.10\\10x=250\\x=250/10\\x=25$

02)

$\frac{5}{10} .\frac{6}{x} \\5x= 6.10\\5x= 60\\x= 60/5\\x=12$

03)

$\frac{12}{x} .\frac{7}{3} \\7x=12.3\\7x= 36\\x=36/7\\x=5,14$

04)

$\frac{80}{x} .\frac{5}{7} \\5x=80.7\\5x= 560\\x=560/5\\x=112$

05)

$\frac{50}{x} . \frac{5}{7} \\5x=50.7\\5x=350\\x=350/5\\x=70$

06)

$\frac{60}{x}.\frac{6}{2} \\6x=60.2\\6x=120\\x=120/6\\x=20$
