\(\frac{23}{14}\times\frac{6}{13}-\frac{9}{14}\times\frac{6}{13}\)
\(=\frac{6}{13}\times\left(\frac{23}{14}-\frac{9}{14}\right)\)
\(=\frac{6}{13}\times1=\frac{6}{13}\)
k mk nha!
=6/13*(23/14-9/14)
=6/13*14/14
=6/13*1
=6/13
\(\frac{23}{14}\)X\(\frac{6}{13}-\frac{9}{14}\)X\(\frac{6}{13}\)
=\(\frac{6}{13}\times(\frac{23}{14}-\frac{9}{14})\)
=\(\frac{6}{13}\times\frac{14}{14}\)
=\(\frac{6}{13}\times1\)
=\(\frac{6}{13}\)
chúc bạn học tốt
