\huge\text{Hey there!}

\text{In order for you to solve this problem, you need to highlight/ underline your}\\\text{ key points to make it more understanding!}

\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\div10=\dfrac{8}{10} = \text{\underlined{answer}}

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

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