"A third is larger than a quarter."
Translation:Triono estas pli granda ol kvarono.
That story actually happened multiple times.
A&W was the first chain that tried to market a slightly bigger burger only to learn that 5 out of 4 Americans have trouble with fractions. ;) McDonalds also tried selling 1/3rd pound Angus burgers in 2007 and 1/3rd pound Sirloin burgers in 2015. None of these 1/3 pound burgers were successful.
“Du trionoj” and “kvin okonoj”. :) http://bertilow.com/pmeg/gramatiko/nombroj/o-vortoj.html#i-3h7
