# How to retag question about percentages?

The tag on this question is "percentile" which is clearly not correct, but I don't know what else to tag it. Any suggestions?

• Then that would leave the question tagless. What tags would be appropriate? – John Jan 31 '14 at 22:18
• I think arithmetic would be appropriate. From the wikipedia article for arithmetic: "The basic arithmetic operations are addition, subtraction, multiplication and division, although this subject also includes more advanced operations, such as manipulations of percentages, square roots, exponentiation, and logarithmic functions." – Antonio Vargas Jan 31 '14 at 22:40
• I thought sure I searched for that one. Anyway ... it's retagged with that. Thanks! – John Jan 31 '14 at 23:24

2. would also do, since the work that the author has shown introduced the abstract variable $X$.
