Not all decimal representations are repeating decimals.
they are called repeating decimals.
Some non-terminating decimals are repeating decimals.
Irrational number or repeating decimal
They are called terminating decimals.
The decimal that never stops is called recurring decimal. For example - 1/3 = 0.3333... and goes on. Such decimals are written with a dot or bar on top of the numbers which are repeating.
a decimal that repeats is called a repeating decimal
The line over a repeating decimal is called the vinculum.
A number that can be expressed as a fraction of two integers is called a rational number. Rational numbers have decimal representations that either terminate (like 0.75) or repeat (like 0.333...). This property distinguishes them from irrational numbers, which cannot be expressed as simple fractions and have non-repeating, non-terminating decimal representations.
They are called rational numbers
It is a recurring or a repeating decimal
a repeating decimal
Decimal numbers that never end but that end up having a repeating pattern are called recurring decimals or repeating decimals.Examples would be 1/3 = 0.33333333...or 452/555 = 0.8144144144144144... (where 144 is the repeating pattern).Reaching that repeating pattern is known as becoming periodic. Only rational numbers will have a repeating pattern. (The repeating pattern may be 00000, as in 4/2 = 2.00000... .)If a decimal number continues forever without having a repeating pattern, then it is a irrational number. One example of a number that continues forever without repeating would be π (pi) which continues infinitely without repeating.Pi is also referred to as a transcendental number.
