| |
| This is a table of English names for positive [[rational number]]s less than or equal to 1. It also lists alternative names, but there is no widespread convention for the names of extremely small positive numbers.
| |
| | |
| Keep in mind that rational numbers like 0.12 can be represented in [[Infinity|infinitely]] many ways, e.g. ''zero-point-one-two'' (0.12), ''twelve [[percent]]'' (12%), ''three twenty-fifths'' <math>\left({3 \over 25}\right)</math>, ''nine seventy-fifths'' <math>\left({9 \over 75} \right)</math>, ''six fiftieths'' <math>\left({6 \over 50}\right)</math>, ''twelve hundredths'' <math>\left({12 \over 100}\right)</math>, ''twenty-four two-hundredths'' <math>\left({24 \over 200}\right)</math>, etc.
