\(2\frac{1}{6}+x:\frac{6}{7}=-75\%\)
\(\frac{13}{6}+x:\frac{6}{7}=-\frac{3}{4}\)
\(x:\frac{6}{7}=-\frac{3}{4}-\frac{13}{6}=-\frac{35}{12}\)
\(x=-\frac{35}{12}x\frac{6}{7}=\frac{5}{2}\)
vậy \(x=\frac{5}{2}\)
\(2\frac{1}{6}+x\div\frac{6}{7}\)\(=-75\%\)
\(\frac{13}{6}+x\div\frac{6}{7}\)\(=-0,75\)
\(\frac{13}{6}+x\div\frac{6}{7}\) \(=-0,75\)
\(\frac{13}{6}+x\) \(=-0,75\times\frac{6}{7}\)
\(\frac{13}{6}+x\) \(=\frac{-9}{14}\)
\(x\) \(=\frac{-9}{14}-\frac{13}{6}\)
\(x\) \(=\frac{-59}{21}\)
