Thats not true with the second one. 65 divided by 26=2.5. There is no such fraction as 1/2.5
actually, what he is saying is that if you take out the 6's it would become 2/5, which is 1/2.5
Perhaps I should clarify ... 19/95 = 1/5 when 9 is removed (19x1/19x5), 26/65 = 2/5 when 6 is removed (13x2/13x5), and 16/64 = 1/4 when 6 is removed (16x1/16x4).

The way i got it was by dividing 19 by 95, and i got .2, which is 1/5, and i did the same for all of them!
great teaser

very nice.
quite unusual.
The only other fraction of 2-digit numbers that can be easily reduced like this is 49/98, although it reduces to 4/8 which is not in the simplest form which is 1/2
I expect to solve all the math teasers, but it was still quite satisfying that I got this one so quickly.
Cool teaser!
