\(\frac{5}{7}.\frac{5}{11}+\frac{5}{7}.\frac{2}{11}-\frac{5}{7}.\frac{14}{11}\)
\(=\frac{5}{7}.\left(\frac{5}{11}+\frac{2}{11}-\frac{14}{11}\right)\)
\(=\frac{5}{7}.\frac{-7}{11}\)
\(=\frac{-5}{11}\)
5/7.5/11+5/7.2/11-5/7.14/11
= 5/7.(5/11+2/11-14/11)
=5/7.-7/11
=-5/11
5/7 + 5/11 + 5/7 . 2/11 - 5/7 .14/11
=5/7.(5/11+2/11-14/11)
=5/7.(5+2-4/11)
=5/7.(-7/11)
=-5/11
\(\frac{5}{7}\times\frac{5}{11}+\frac{5}{7}\times\frac{2}{11}-\frac{5}{7}\times\frac{14}{11}\)
\(=\frac{5}{7}\times\left(\frac{5}{11}+\frac{2}{11}-\frac{14}{11}\right)\)
\(=\frac{5}{7}\times\frac{-7}{11}\)
\(=\frac{-5}{11}\)
_Chúc bạn học tốt_
5/7.5/11+5/7.2/11+5/7.14/11
=5/7(5/11+2/11-14/11)
=5/7.(-7/11)
=-5/11
giải nhanh giúp mình nha! 5/7.2/11+5/7.12/11-5/7.7/11
