A simple fraction (also known as a common fraction or vulgar fraction, where vulgar is Latin for "common") is a rational number written as a / b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 2 , − 8 5 , −8 5 , and 8 −5 .
99.3 is "ninety-nine point three"; or "ninety-nine and three tenths" (U.S., occasionally). In English the decimal point was originally printed in the center of the line (0·002), but with the advent of the typewriter it was placed at the bottom of the line, so that a single key could be used as a full stop/period and as a decimal point.
Decimal fractions (sometimes called decimal numbers, especially in contexts involving explicit fractions) are the rational numbers that may be expressed as a fraction whose denominator is a power of ten. [8] For example, the decimal expressions ,,,, represent the fractions 4 / 5 , 1489 / 100 , 79 / 100000 , + 809 / 500 ...

The general characteristics of the number formation rules in Romanian are: The numeration base used is decimal. Word order is big-endian with the exception of numbers from 11 to 19. Large numbers use a combined form of the long and short scales. Connection words are used in certain situations.
The Romans used a duodecimal rather than a decimal system for fractions, as the divisibility of twelve (12 = 2 2 × 3) makes it easier to handle the common fractions of 1 ⁄ 3 and 1 ⁄ 4 than does a system based on ten (10 = 2 × 5).
Use a colon (spaced) when one or more decimal points is present (a 3.5 : 1 ratio (markup: a 3.5 : 1 ratio)). Do not use the colon form where units are involved (dissolve using a 3 ml : 1 g ratio)—instead see ratios section of table at § Unit names and symbols, below.
