we can figure out how many light bulbs are broken by looking at the wording of the question
13% of 900 lightbulbs were broken
the word "of" is referring to multiplication
so we can multiply 13% by 900

900 * .13 = 117

117 lightbulbs out of 900 were broken

this could also be written as 

117/900

hope this helped!

To find 13% of 900, you need to convert the percent to a decimal.
13/100 = 0.13

Then, you do 900 * 0.13 = 117

117/900 light bulbs were broken
