Tìm các số a,b,c. Biết: 0,abc x 100= 8,1x10+4,4

Answer 1

\(\overline{0,abc}.100=8,1.10+4,4\)

\(\overline{0,abc}.100=85,4\)

\(\overline{0,abc}=85,4:100\)

\(\overline{0,abc}=0,854\)

Vậy a=8 , b=5 , c=4

Answer 2

\(\overline{0,abc}\times100=8,1\times10+4,4\)

\(\overline{0,abc}\times100=81+4,4\)

\(\overline{0,abc}\times100=85,4\)

\(\overline{0,abc}=85,4\div100\)

\(\overline{0,abc}=0,854\)

\(\Rightarrow a=8\)

\(b=5\)

\(c=4\)
