if I have around 9 5-day weeks or 65 days to complete 116 assignments how many assignments do I do for every 5 day week, every day, even tell me how many to do every month

You have:

If you consider working weekends as well:

For assignments to do for every 5-day week :

9 weeks = 116 assignments

∴ For every week = 116/9 = 13 assignments

For assignments to do for every day :

9 weeks = 116 assignments

We have 5 days in 1 week

∴ 9 weeks = 9 × 5 = 45 days

∴ For every day = 116/45 = 3 assignments (approx.)

For assignments to do for every month :

1 month = about 30 days

∴ 65 days = 2 months 5 days = 2.2 months (approx.)

∴ For every month = 116/2.2 = 52 assignments (approx.)
