Cathy can do a job in 8 hours while Danny can do the same job in 6 hours. Cathy and Danny work together for three hours.
what fraction of the job is left to be finished?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

In 3 hours, Cathy made 3%2F8 of the job, while Danny made 3%2F6 = 1%2F2 of the job.

Together, they made 3%2F8+%2B+1%2F2 = 3%2F8+%2B+4%2F8 = 7%2F8 of the job.

Answer. 1%2F8 of the job remains to be finished.
