Percentage... This page needs major editing to make it consistent with strict mathematical thinking, not 'street' talk. Not distinguishing between percent(%) and percentage is analogous to not distinguishing between a subject pronoun (I, we, he, she, they) and an object pronoun (me, us, him, her, them).

You accept standard English: "For me, I believe you know the grammatical difference between the use of a subject pronoun versus an object pronoun." Would you accept the following? "For I, me believes you know the grammatical difference between the use of a subject pronoun versus an object pronoun."

This is the same issue with the distinction between a percent (a ratio based on 100, which can be written in its decimal notation, or its transformed notation using the percent symbol (%). Since the percent has been identified as that numeral with a special attached symbol (%), it can not suddenly be named a percentage.

A percentage is either a count (number of students) or measurement (money) numeral, which is the result of acting on a base number (same in type as the percentage numeral) by transforming that base numeral to the base of 100. For example: $6400 invested at 2.5% results in an outcome of $160. This $160 is the percentage. So $160/$6400 = 2.5/100 (or 0.025 or 2.5%) The strict mathematical form is an equivalence [think =):  (P$/$6400) = (2.5/100) So P = (2.5)(6400)/100. This P value is the percentage. In this case, this numeral has a dollar symbol ($, same as the initial base numeral), NOT a percent symbol (%). After all that numeral was already used (see 2.5%)

Percentage is Different from percent(%) The example opening used is an immediate contradiction: 45% is read as forty-five percent. It then cannot be stated as percentage. Example 2 Again violates strict mathematical use of two distinct words, notation, and concepts. It is stated: " expressed as a percentage, this is a 6% increase". WAIT...6% is read as six percent. It cannot suddenly become six percentage.

The percentage page is in need of major strict mathematical editing. At present it is randomly inconsistent, i.e. occasionally it's mathematically accurate, and then at others it is not.
