If I want to write I got 80 percent, which of these two is the correct way to do so?
I passed with a percentage of 80.
I passed with the percentage of 80.
Please this this answer.
You seem to want to say your percentage was eighty, or that you had an 80 percentage. That really isn't something we say, even to the point of being ungrammatical — so, “wrong” to our ears.
If you got 80%, then you simply write
If you want to spell that out using words not symbols, the correct way is:
That’s because “80” is read as eighty and “%” is read as percent. Some style guides say never to write out the number as a word, even if you do spell out the symbol:
You seem to want to say more than just that you got 80%, but also that you passed. This would be fine:
But so would this:
I suppose you could skip the word score and reduce that to this, while preserving the indefinite article:
That’s a bit casual; it takes more context to be understood.
The word percentage should not be used with a number preceding it. It’s a noun not a rate the way percent is, and so it likes adjectives or non-numeric determiners in front of it, not cardinal numbers. These are all correct:
Those would all be wrong if they read percent instead of percentage.
It is vaguely possible that you are trying to say that you were in the 80ᵗʰ percentile. Percentile is a bit different. If you need to hit the 80ᵗʰ (eightieth) percentile to pass, then any score that’s 80% or better passes.
In other words, only the top quintile would be considered passing.
