Hi There!
Since there are 180 school days and Holly missed 7 then she attended [tex] \frac{173}{180} [/tex] days.
So, to find out the percent of school days she attended school you have to divide 173/180, 173 represents school days she attended or numerator, and 180 represents total school days the denominator. Once you divide 173/180 you should get 0.96111111111, but if you round it, the answer will be 96%.
Steps
1. Divide 173/180= 0.96111111111
2. Round you're answer 0.96111111111
Final Answer- Holly attended 96% percent of school days.
Hope This Helps:)
