Question

\(\overline{a,bc}+\overline{ab,c}=21,12\)

Answer 1

\(\overline{a,bc}+\overline{ab,c}=21,12\)

\(\overline{abc}\) x \(0,01+\overline{abc}\) x\(0,1=21,12\)

\(\overline{abc}\) x \(\left(0,01+0,1\right)=21,12\)

\(\overline{abc}\) x \(0,11=21,12\)

\(\overline{abc}=21,12:0,11\)

\(\overline{abc}=192\)
