I know when comparing two things using multiplicative numerals, some usages like the following sentences are possible.

This book is twice the price of that book.
This book is twice as expensive as that book.

I wonder if this rule also applies to fractions such as one-third or one-tenth.

This book is one-third the price of that book.
This book is one-third as expensive as that book.

    You're exactly right. If one book costs $10, that means that another book that is one-third as expensive (or one-third of the price) would cost $3.33. – A. Galloway Jul 25 '17 at 17:38

Yes, your example sentences are fine. You can also say "a third" or "a tenth":

This book is a third of the price of the other book.

If you go to my brother's shop, you can get that outfit for less than a tenth of the retail price.
