I'm learning how to write graph reports, so could you help me with the use of percentage, proportion and rate.

For example, is it correct to write:

1. The percentage of males enroling in the course was 30%

2. The percentage of males enroling in the course was 30 (without "%")

And, can "proportion" and "rate" be used interchangeably with "percentage"? For example: The proportion / rate of males enroling in the course was 30%

Thank you.

You should use the symbol "%" at all times if you are referring to a percentage. Also, please note that "enrolling" is written with double "l" in AmE.

You can use "proportion," but not "rate," because you are comparing males and females, and "rate" expresses an absolute value. Instead, "percentage" and "proportion" refer to a portion within a whole.
