Question

tập hớp các số nguyên x thỏa mãn \(\frac{1}{2}\)-(\(\frac{1}{3}\)+\(\frac{3}{4}\))< x <\(\frac{8}{3}\)-(\(\frac{1}{5}\)+\(\frac{3}{4}\)) là S ={.......................................}

Answer 1

\(\frac{1}{2}-\left(\frac{4}{12}+\frac{9}{12}\right)=\frac{1}{2}-\frac{13}{12}=\frac{6}{12}-\frac{13}{12}=-\frac{7}{12}=-0,58\left(3\right)\)

\(\frac{8}{3}-\left(\frac{4}{20}+\frac{15}{20}\right)=\frac{8}{3}-\frac{19}{20}=\frac{160}{60}-\frac{57}{60}=\frac{103}{60}=1,71\left(6\right)\)

=> x = { 0; 1 }
