Answer 1

\(\overline{120ab}:376=\overline{ab}\)

\(\Rightarrow\overline{120ab}:\overline{ab}=376\)

\(\Rightarrow(12000+\overline{ab}):\overline{ab}=376\)

\(\Rightarrow12000:\overline{ab}+\overline{ab}:\overline{ab}=376\)

\(\Rightarrow12000:\overline{ab}+1=376\)

\(\Rightarrow12000:\overline{ab}=376-1\)

\(\Rightarrow12000:\overline{ab}=375\)

\(\Rightarrow\overline{ab}=12000:375\)

\(\Rightarrow\overline{ab}=32\)
