I use the language that I think my interlocutor would prefer. If I don’t know, then I default to the language of the social context, unless I specifically want to practise a language at that moment. If I want to practise, then I ask first.
Cool. Peace.
Sure.
If you had more of an intuition for metric units, then it wouldn’t occur to you to think of “4 feet” as something to optimize for. It means nothing. It’s an entirely arbitrary preference. You’d just think “a metre and a half” and you wouldn’t have to grope for “syllables” as a rationalization for it.
Your preferences mean nothing. You prefer what’s familiar, just like everyone else.
If “close enough” works, then it’s nice to have the skill. Having the skill requires occasionally using it.
Where accuracy is important, since we almost always have a calculator with us now, that’s a no-brainer.
Maybe more to the point, though, understanding how percentages work is wise. It’s one of the few arithmetic topics that we encounter regularly in life.
In this case, 23% of 53 and 53% of 23 each have their own little trick, depending whether you’d rather overestimate a little with 1/4 of 52 or underestimate a little with half of 24. I find it handy to be able to think that way, especially for example when trying to get out of a taxi and paying cash.
Pretty close to 1/4 of 52, so like 13-ish, but maybe closer to 12.
You don’t mess with the Zohran.
You might be done with people, not the internet.
