expressing fractions of people?


One pronounces "two people" as 二人【ふたり】, but what happens with "2.7 people"? Is
the following reading of this sentence correct?

>
> このうち[2.7]{にてんなな}人【にん】に1人【ひとり】が「重【おも】い荷物【にもつ】を背負【せお】うことがおっくうで登校【とうこう】を嫌【いや】がった経験【けいけん】がある」と答【こた】えた

_Of these, 1 in 2.7 said that they had an experience of disliking going to
school because they felt uncomfortable carrying a heavy bag on their back._

Yes, 2.7人 is read にてんななにん. In this case, I don't see why one can't rewrite it
as 100人に37人 instead, though. (Perhaps because that would be too long?)

As for the pronunciation, the prolonged にーてん might be more common, but I think
that's besides the point.




It's somewhere between 2人に1人 (1/2 = 0.5 = 50%) and 3人に1人 (1/3 = 0.33 = 33%).
1/2.7 is 0.37, so you can understand 2.7人に1人 as "3.7 in 10" or "37% of them".
This type of expression is not unique to Japanese, but it's used mainly in
academic writings.

**EDIT:** As for the pronunciation, it's に **い** てんななにんにひとり. [に has to be
elongated](https://japanese.stackexchange.com/a/56517/5010).
