A project manager has determined that 3/10 of the work for a project was completed in 9 days. How many more days

will it take to finish the project if the work continues to progress at the same rate?

30 days

Step-by-step explanation:

3/10 is completed in 9 days, so 6/10 in 18 days and 9/10 in 27 days.

If it only takes 9 days for 3/10, then 9 divided by 3 = 3. The final 1/10 is completed in 3 days. This all equals 30 days.

I could be wrong, but that's what I think.
