class starts at 10:29am and ends at 11:14am. If you cam in 35 minutes late , what percent of class did you miss ?

OpenStudy (anonymous):

so u need to figure out how long class is

OpenStudy (anonymous):

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):

where did u get 1000

OpenStudy (anonymous):

that was 10x100 but u should do 35x100 that was a mistake but the answer is the same

OpenStudy (anonymous):

3500?

OpenStudy (anonymous):

so |dw:1314406763559:dw|
