Question

8/7+4/7.-6/11-4/7.5/11

Answer 1

\(\frac{8}{7}+\frac{4}{7}\cdot\left(-\frac{6}{11}\right)-\frac{4}{7}\cdot\frac{5}{11}\)

\(=\frac{8}{7}+\frac{4}{7}\cdot\left(-\frac{6}{11}-\frac{5}{11}\right)\)

\(=\frac{8}{7}-\frac{4}{7}\)

\(=\frac{4}{7}\)

Answer 2

thế còn con nữa đâu bạn

Answer 3

\(\frac{8}{7}+\frac{4}{7}.\left(-\frac{6}{11}\right)-\frac{4}{7}.\frac{5}{11}\)

\(=\frac{8}{7}+\frac{4}{7}.\left(-\frac{6}{11}-\frac{5}{11}\right)\)

\(=\frac{8}{7}-\frac{4}{7}.-1\)

\(=\frac{8}{7}+\frac{4}{7}\)

\(=\frac{12}{7}\)

Answer 4

8 /7 + 4 / 7 . ( -6 ) / 11 - 4 / 7 . 5 / 11

= 8 / 7 + 4 /7 . ( -6 / 11 - 5 / 11 )

= 8 / 7 - 4 / 7

= 4 / 7

Học tốt nhé
