What is $0.4\overline 8+0.3\overline 7\ ?$

Hello Guest

$0.4\overline 8+0.3\overline 7=0.8\overline 6\\$

$100\cdot 0.8\overline6=86.\overline6$

- $10\cdot 0.8\overline6=\ 8.\overline6$

  $\overline{90\cdot 0.8\overline6=78}$

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