Fractions

Fractions are mathematical text symbols (we will talk later about their meaning) that people had been texting from the times when ASCII encoding was developed. And you can type them right from your keyboard. I'll show you how to do it by using different techniques depending on your Operating System and tastes.

Fractions on blackboard

Fraction represents a part of a whole or, more generally, any number of equal parts. O we can also say that fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

A simple fraction (for example ½) consists of an integer numerator, displayed above a line (or before a slash), and a non-zero integer denominator, displayed below (or after) that line. The numerator represents a number of equal parts and the denominator indicates how many of those parts make up a whole. Fractional numbers can also be written without using explicit numerators or denominators, by using decimals, percent signs, or negative exponents (as in 0.01, 1%, and 10−2 respectively, all of which are equivalent to 1/100).

Other uses for fractions are to represent ratios and to represent division. So the fraction ¾ is also used to represent the ratio 3:4 (the ratio of the part to the whole) and the division 3 ÷ 4 (three divided by four).
