Title: link to an analysis about fractions
Post by Christine on Dec 13^th, 2012, 3:40pm

Hi,
I'm searching for a link to a paper about fractions where the numbers of the fractions(numerator and denominator) are found in the decimal representation

e.g. 5/2 = 2.5

I saw that paper months ago, but I lost the link and couldn't find again - maybe it was in OEIS files.

That paper described many such examples.

With 1-digit number, the only case is 5/2 = 2.5
Many examples with larger numbers.

Any ideas?

I found a link that mentions it:

How many rational numbers a/b are there (with a and b relatively prime) such that a/b = b.a

http://mathforum.org/wagon/fall05/p1036.html

the link to [View the solution] is not found

Can anyone provide other links?
