I have the figures below.

2791 Potential Customers and 45 Enrolled Customers

I computed the percentage in Excel as 45/2791, which gave me 16.12, but a calculator gave me 0.0161.

I'm not sure what you mean. Additionally, I checked "set Precision as presented," yet I still get the wrong percentages. Do you know why?

When I calculated 45/2791 multiplied by 100, the answer wasn't right, but when I calculated 45/2791 multiplied by 0.10, the answer was right on the money.

Any settings I should modify? Please inform me.
