What is \(0.4\overline 8+0.3\overline 7\ ?\)

 

Hello Guest

 

\(0.4\overline 8+0.3\overline 7=0.8\overline 6\\\)

\(100\cdot 0.8\overline6=86.\overline6 \)

- \(10\cdot 0.8\overline6=\ 8.\overline6\)

  \(\overline{90\cdot 0.8\overline6=78}\)

 

\(0.4\overline 8+0.3\overline 7=0.8\overline 6=\dfrac{78}{90}=\color{blue}\dfrac{13}{15}\)

laugh  !
