- Irreducible fraction - Wikipedia
Irreducible fraction An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered) [1]
- Decimal representation - Wikipedia
A decimal representation of a non-negative real number r is its expression as a sequence of symbols consisting of decimal digits traditionally written with a single separator: Here is the decimal separator, k is a nonnegative integer, and are digits, which are symbols representing integers in the range 0, , 9 Commonly, if The sequence of the —the digits after the dot—is generally
- Fraction - Wikipedia
A decimal fraction is a fraction whose denominator is an integer power of ten, commonly expressed using decimal notation, in which the denominator is not given explicitly but is implied by the number of digits to the right of a decimal separator
- Numeral system - Wikipedia
Numbers written in different numeral systems A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner The same sequence of symbols may represent different numbers in different numeral systems For example, "11" represents the number eleven in the decimal or base
- Decimal - Wikipedia
Decimal may also refer specifically to the digits after the decimal separator, such as in " 3 14 is the approximation of π to two decimals " The numbers that may be represented exactly by a decimal of finite length are the decimal fractions That is, fractions of the form a 10n, where a is an integer, and n is a non-negative integer
- Decimal data type - Wikipedia
Some programming languages (or compilers for them) provide a built-in (primitive) or library decimal data type to represent non-repeating decimal fractions like 0 3 and −1 17 without rounding, and to do arithmetic on them

- Ratio - Wikipedia
As for fractions, the simplest form is considered that in which the numbers in the ratio are the smallest possible integers Thus, the ratio 40:60 is equivalent in meaning to the ratio 2:3, the latter being obtained from the former by dividing both quantities by 20 Mathematically, we write 40:60 = 2:3, or equivalently 40:60∷2:3
