Answer: in explanation
Step-by-step explanation
Sandi can perform  1/9 of the task in a day
Eva can perform 1/5 of the task in a day
Working together, they can perform
                                                             1/9 + 1/5 of the task per day
                                                             = 5/45 + 9/45 = 14/45 of the task in a day
or                                                             45/14 days in the task = 3.2 days
So
           It would take about 3.2 days to complete the task working togethe
