$\huge\text{Hey there!}$

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

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

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

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

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

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

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

If 8 good and 2 burned out,
10 in total,
