Gọi số thập phân cần tìm là \(\overline{A,b}\) theo đề bài ta có
\(\overline{A,b}-\overline{A,12b}=0,177\)
\(\Rightarrow1000x\left(\overline{A,b}-\overline{A,12b}\right)=1000x0,177\)
\(\Rightarrow\overline{Ab00}-\overline{A12b}=177\)
\(\Rightarrow1000xA+100xb-1000xA-120-b=177\)
\(\Rightarrow99xb=297\Rightarrow b=297:99=3\Rightarrow A=3x4=12\)
\(\Rightarrow\overline{A,b}=12,3\)
