I know that you can pronounce a fraction using the -ono suffix. However, in some situations it can be hard to parse; for example 2/10 is pronounced du dekonoj but can be mistaken for dudekonoj, that is 1/20. Is there another way to say fractions aloud?

  • 12 / 10 = dekdu dekonoj = 12 dividite de 10 (3 syllables more)
  • 10 / 20 = dek dudekonoj = 10 dividite de 20

Difference only audible by the pause for onoj. However pauses are a bit more used in E-o as in English - I think.

It would have been nice to have a shorter expression for dividite de (per/super?) but that is as it is.

For clearness by audio channel with noice (radio, phone), one can use the following trick:

  • 12 / 10 = dekdu da dekonoj
  • 10 / 20 = dek da dudekonoj

  • If I need to speak out polynomials or formulas with a division in la espa, I use super. So (x^2 + y^2) / (x-y) is spoken as "en krampoj ikso en kubo plus ipso en kubo fino de krampo super en krampoj ikso minus ipso fino de krampo" Sep 23 '19 at 14:50
  • @JuhaMetsäkallas 5 super 2= 5 over 2= 5! 4! 3! 2! 1! / 2! 1! 3! 2! 1!. Eble iuj mallongigas "dividite de" per "per" - tamen mi ne havas spertojn kun matematikistojn esperantajn.

  • Mi scias, ke oni minimume en la angla kaj en la sveda uzas over resp. över ĉi tiel kun du sencoj: 5 over 2 = 5/2 or 5 over 2 = 5! / ((5-2)! 2!). Eble oni faras ĉi tiel ankaŭ en la espa. Sep 26 '19 at 12:40
