Okay, so seems that the debate on this is a generational thing. The meme is backwards because it's the grey-haired guy who should be saying 1, not the younger women.
Basically, if you were taught older conventions like I was (being an old fart), you would divide the 6 by the product of everything to the right of the division, because you would treat the ÷ as a /, and treat the product as a denominator.
We used to treat ÷ as an easier way to write out a fraction problem, but that is no longer.
これマジか。「1」と回答するのは昔の人らしい。除算記号「÷」は世界的にもう使われてないらしい。知らなかった！ 確かにPCで出そうとすると面倒。 #fedibird

2009年に国際標準化機構（ＩＳＯ）が発行した数学の記号に関する国際規格「ＩＳＯ 8000－2」では、割り算は「／」か分数によって表すと定めた上で、「割り算を表す記号として『÷』は使うべきではない」とはっきり書かれている。
