Question

7/13 * 5/9 +7/13 *8/9 - 14/26 * 13/9

làm nhanh mik tick

Answer 1

\(\frac{7}{13}.\frac{5}{9}+\frac{7}{13}.\frac{8}{9}-\frac{14}{26}.\frac{13}{9}\)

\(=\frac{7}{13}.\frac{5}{9}+\frac{7}{13}.\frac{8}{9}-\frac{7}{13}.\frac{13}{9}\)

\(=\frac{7}{13}.\left(\frac{5}{9}+\frac{8}{9}-\frac{13}{9}\right)\)

\(=\frac{7}{13}.0\)

\(=0\)

_Chúc bạn học tốt_

Answer 2

ai tích mình mình tích lại cho

Answer 3

đáp án bằng 0 nha bạn

Answer 4

\(\frac{7}{13}\times\frac{5}{9}+\frac{7}{13}\times\frac{8}{9}-\frac{7}{13}\times\)\(\frac{13}{9}\)

\(=\frac{7}{13}\times\frac{5}{9}+\frac{7}{13}\times\frac{8}{9}-\frac{7}{13}\times\frac{13}{9}\)

\(=\frac{7}{13}\times\left(\frac{5}{9}+\frac{8}{9}-\frac{13}{9}\right)\)

\(=\frac{7}{13}\times0\)

\(=0\)

        ~~~Hok tốt~~~

Answer 5

\(\frac{7}{13}\cdot\frac{5}{9}+\frac{7}{13}\cdot\frac{8}{9}-\frac{14}{26}\cdot\frac{13}{9}=\frac{7}{13}\cdot\frac{5}{9}+\frac{7}{13}\cdot\frac{8}{9}-\frac{7}{13}\cdot\frac{13}{9}=\frac{7}{13}\cdot\left(\frac{5}{9}+\frac{8}{9}-\frac{13}{9}\right)=\frac{7}{13}\cdot0=0\)
