tim x 
a)x/5<3/7

b)1<11/x<2

Answer 1

a) 2/5 < 3/7

b) 1 < 11/6 < 2

Answer 2

a) \(\frac{x}{5}< \frac{3}{7}\)

\(\Rightarrow x< \frac{15}{7}\)

\(\Rightarrow x< 2\frac{1}{7}\)

\(\Rightarrow\) x = 0 ; 1 ;2

b) \(1< \frac{11}{x}< 2\)

\(\Rightarrow\frac{11}{11}< \frac{11}{x}< \frac{11}{5,5}\)

\(\Rightarrow11>x>5,5\)

\(\Rightarrow x=10;9;8;7;6\)
