Giúp mình nhé : Tính bằng 2 cách :
\(a,\left(\frac{6}{11}+\frac{5}{11}\right)x\frac{3}{7}\)
\(b,\frac{3}{5}x\frac{7}{9}+\frac{3}{5}x\frac{2}{9}\)

giúp mik nha
Tính bằng cách thuận tiện
\(\frac{12}{23}\times\frac{9}{28}+\frac{11}{23}\times\frac{9}{28}=\)
\(3+\frac{1}{9}+\frac{3}{9}+2+\frac{5}{9}+3+2=\)
