Irrational Numbers

# Are all non-terminating decimals irrational numbers?

No.

0.33333... repeating = 1/3

0.428571... repeating = 3/7

0.11111... repeating = 1/9

0.090909... repeating = 1/11

Those decimals are all non-terminating, but the numbers are all rational.

No, they are not. Recurring decimals are rational.

Not at all. 0.33333... nonterminating = 1/3 rational 0.66666... nonterminating = 2/3 rational 0.1428571428... nonterminating = 1/7 rational 0.55555... nonterminating = 5/9 rational

No integers are irrational numbers. An integer is a whole number, positive or negative. This means they have no decimals or fractions. An irrational number, however, is a number with fractions or decimals. Therefor, there are no integers that are irrational numbers.

.333333333...; .999999999999...; .666666666666666...; etc. All irrational numbers, basically.

No. All natural numbers are whole, so they are rational. Irrational numbers like pi and the square root of 34 come in decimals.

All rational numbers can be converted from decimals to fractions as for example 0.75 = 3/4 but irrational numbers can not be converted from decimals to fractions.

No, they could not. Irrational numbers are also decimal numbers.

Infinitely many. pi is not just an irrational number but a transcendental number. All irrational numbers have infinite decimals that do not go into a recurring pattern.

All irrational numbers are non-terminating decimals that can't be expressed as fractions

Yes, except that all irrational numbers will be non-terminating, non-repeating decimals.

No because non-repeating decimals may be terminating.But suppose you consider terminating decimals as consisting of repeating 0s. That is, 1/8 = 0.125 = 0.12500....Then all non-repeating decimals are irrational.

Germany is the name of a country and so does not have repeating decimals.

All irrational numbers are real, but not all real numbers are irrational.

Some are and some are not.Decimal fractions which are neither terminating nor recurring represent irrational numbers.A fraction in the form of a ratio, in its simplest form, where either the numerator or the denominator is irrational (or both) are irrational.

only decimals that never end and never repeat are irrational. a decimal is rational if it can be written as a fration or ratio of two numbers. for example: .3434343434343434... 100x=34.34343434... -x 99x=34 34/99

Real numbers are all numbers which do not contain "i", when "i" represents the square root of -1. All numbers which do contain "i" are "imaginary numbers" and are not real numbers. This means that all numbers you'd ordinarily use are real numbers - all the counting numbers (integers) and all decimals are real numbers. So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers - including irrational decimals such as pi.

All rational and irrational numbers are real numbers.

No irrational numbers are whole numbers,and all whole numbers are rational.

Because decimal numbers that can't be expressed as fractions are irrational numbers whereas all rational numbers can be expressed as decimals or fractions.

No. If they are recurring, then they are rational.

No. All irrational numbers are real, not all real numbers are irrational.

All numbers can be changed from fractions to decimals.

No, -3 is a rational number. All fractions are rational along with all decimals that terminate or repeat. (this applies to both positive and negative numbers.)

Ye it is true that all irrational numbers are real numbers that can't be expressed as fractions.
