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!
