A half smaller than?

Say, A and B are some quantities or sizes and A=3B.

Regarding the usage of comparative forms, which one sounds right?

1) B is 1/3 times smaller than A. (B is one-third smaller than A.)
This is very ineresting, since "1/3 times smaller" would actually mean 3 times bigger, wouldn't it? (Otherwise, "smaller" is redundant or not meaningful.)

2) B is 3 times smaller than A.
A=4B, maybe?

3) B is 2 times smaller than A.
This does not sound natural, but think about "B is 1 time smaller than A", which must mean A=2B (If A=B then there's no comparison!), therefore, "1" actually means "2" here. So for 3), 2 means 3, and A=3B.

I know should write properly like "A is 3 times as much as B." or "B is one-third as much as A." But wondering how popular 1)-3) occur in every sort of text.

I like this question. It made me think. I don't think I have ever heard 1)-3), and I don't think they are acceptable or understandable.

  • I like this question.
  • It made me think.
  • I don't think I have ever heard 1)-3), and I don't think they are acceptable or understandable.
  • But the parenthetical statement in 1), (B is one third smaller than A), is OK.
  • This would be B=A-1/3A or B=2/3A.

That's a good point. So can I infer that it's clear that the below means B=4A?

B is 3 times greater than A?

I'm wondering if 1/3 goes with smaller than or 3 goes with greater than would create less ambiguity?

No. B=3A, B is 3 times greater than A. Here, as you might notice, 'greater than' is redundant.
