'''99/80''', the '''undecimal submajor third''', also known as the '''cake third''', is [[45/44]] flat of the [[81/64|Pythagorean major third (81/64)]], and also [[100/99]] flat of the [[5/4|classical major third (5/4)]], while being [[8019/8000]] sharp of the [[100/81|grave major third (100/81)]]. The alternate name, ''cake third'', refers to the fact that tempering out 45/44, the cake comma, leads to a temperament that slices 99/80 exactly in half (into two [[11/10]]'s). It arises in [[just intonation]] as the sum of a [[9/8]] whole tone and an [[11/10]] submajor second. It is also [[2080/2079]] flat of [[26/21]].

~~'''99/80''', the '''undecimal submajor third''', also known as the '''cake third''',~~ is exactly [[8/7]] flat of the very accurate half-octave of [[99/70]], and so is accurately represented in any even edo with a good ~~7, of which the first truly good example is~~ [[~~26edo]]. The alternate name, ''cake third'', refers to the fact that tempering out [[45~~/44]], ~~the cake comma, leads to a temperament that slices 99/80 exactly in half (into two~~ [[~~11/10]]s).~~

== Approximation ==

This interval is exactly [[8/7]] flat of the very accurate half-octave of [[99/70]], and so is accurately represented in any even edo with a good [[7/1|7]], such as [[26edo]].

~~It is the sum of a [[9/8]] whole tone and an [[11/10]] submajor second, and so is [[8019/8000]] sharp of [[100/81~~]].
