If 8 good and 2 burned out,

\text{We have 8 that are in good condition}\ \checkmark


\text{2 of them that are burned out.}\ \checkmark


\text{8 + 2 = 10, so 10 would be partial (total \#)}


\text{The number of 8 of the bulbs will be your front number or (numerator)}


8/10=(8)/(10) = \text{\underlined{answer}}


\boxed{\boxed{\bf Answer:{(8)/(10)\ or \ your\ can\ just\ simply\ say \ 80\%}}}}\checkmark


\text{Good luck on your assignment and enjoy your day!}
