i got 77.7 % because class is 45 min long and you were only there 10 min so u set up the proportion 10/45=x/100 which is 1000=45x

OpenStudy (anonymous):
45 minutes long now what ?

OpenStudy (anonymous):
look at my math set up the proportion than solve

OpenStudy (anonymous):
wait i messed up u want how long u were not there so it is 35/45 but the answer is the same

OpenStudy (anonymous):
