Question

\(\frac{5}{9}.\frac{6}{5}+\frac{18}{20}.\frac{6}{5}\)

Answer 1

mk lộn

6/5.(5/9+18/20)

=6/5.131/90

=131/75

 k mk nha

Answer 2

6/5.(5/9+18/20)

=6/5.131/90

=239/90

Answer 3

 \(\frac{5}{9}.\frac{6}{5}+\frac{18}{20}.\frac{6}{5}=\frac{5.6}{9.5}+\frac{9.6}{10.5}\)

\(=\frac{6}{9}+\frac{27}{25}\)Sau đó quy đồng rồi tính tiếp nha bạn :))

Answer 4

\(\frac{5}{9}\)\(.\)\(\frac{6}{5}\)+\(\frac{18}{20}\)\(.\)\(\frac{6}{5}\)\(=\)\(\frac{2}{3}\)+\(\frac{27}{25}\)\(=\)\(\frac{131}{75}\)

Answer 5

\(\frac{5}{9}\cdot\frac{6}{5}+\frac{18}{20}\cdot\frac{6}{5}=\frac{6}{5}\cdot\left(\frac{5}{9}+\frac{18}{20}\right)=\frac{6}{5}\cdot\frac{131}{90}=\frac{131}{75}\)

Answer 6

\(\frac{5}{9}x\frac{6}{5}+\frac{18}{20}x\frac{6}{5}=\left(\frac{5}{9}+\frac{18}{20}\right)\)\(x\frac{6}{5}\)

                                   \(=\left(\frac{100}{120}+\frac{162}{120}\right)x\frac{6}{5}\)              

                                    \(=\frac{262}{120}x\frac{6}{5}\)                   

                                      \(=\frac{1572}{600}\)

                                       \(=\frac{131}{50}\)
