a,\(\frac{1}{x-1}+\frac{-2}{3}.\left(\frac{3}{4}-\frac{6}{5}\right)=\frac{5}{2-2x}\)
\(\Rightarrow\frac{1}{x-1}+\frac{-2}{3}.\left(\frac{3}{4}-\frac{6}{5}\right)=\frac{5}{2-2x};Đkxđ:x\ne1\)
\(\Rightarrow\frac{1}{x-1}+\frac{-2}{3}\left(\frac{-9}{20}\right)=\frac{5}{2-2x}\)
\(\Rightarrow\frac{1}{x-1}+\frac{3}{10}=\frac{5}{2-2x}\)

A = (19\(\frac58\) : \(\frac{7}{12}\) - 13\(\frac14\): \(\frac72\)) x \(\frac45\) (xem lại đề bài)
B = (9\(\frac{30303}{80808}\) + 7\(\frac{303030}{808080}\)) + 4,03
B = (9\(\frac38\) + 7\(\frac38\)) + 4,03
B =(9 + 7) + (\(\frac38+\frac38\)) + 4,03
B = 16 + 3/4 + 4,03
B = 16 + 0,75 + 4,03
B = 16,75 + 4,03
B = 20,78
