Square root of 2...
If a number consists of a series of non repeating and non terminating digits then it is irrational.A particularly well known example is that of pi (which is an irrational number representing the proportion between the diameter of a circle and its circumference).
Irrational numbers are decimal numbers that can't be expressed as fractions. An example is the square root of 2
Not necessarily. Remember that the definition of an irrational number is a number that can't be expressed as a simple fraction. 2/3, for example, is rational by that definition even though its decimal form is a repeating decimal. Since irrational numbers cannot be written as fractions, they don't have fraction forms. So basically, numbers with repeating decimals are considered rational. Irrational numbers don't have repeating decimals.
Both rational and irrational numbers can be expressed with decimals. If the number is irrational, it will have an infinite number of decimal digits, and there will be no periodic repetition. For example, 1/7 (which is rational) is 0.142857 142857 142857... The same sequence of six digits repeats over and over again. In irrational numbers, this is not the case.
An irrational number cannot be written as a fraction or to an exact decimal such as the symbol for pi or the square root of two. A rational number can be written in the form of a fraction or a decimal to an exact value.
Yes.
A nonterminating number does not end. An example is the fraction 1/3. When written as a decimal, it is a nonterminating number. Also pi is a nonterminating number. Some nonterminating numbers are repeating, some are nonrepeating. But they just don't end.

An Irrational Number is a Number that cannot be converted to a Fraction and has an unstoppable amount of numbers after the decimal point. For Example, Pi is the most famous irrational number. If I didn't answer your question, search up Irrational Numbers.
Both can be either. For example, 1.4 is a rational decimal. 1.41421356 (...) is the decimal representation for sqrt(2), an irrational. 2/5 is a rational fraction. sqrt(2)/3 is an irrational fraction.
A terminating decimal is a decimal number with a definite end. For example, pi has no end and is irrational. 25.33 has an end and is therefore a terminating decimal.
If you write an irrational number as a decimal, you would have an infinite number of decimal places, and the digits wouldn't repeat. That is, if you divide 1 by 7 for example, you get the pattern 0.142857 142857 142857... repeating over and over; this won't happen with an irrational number.All irrational numbers are decimals which can not be expressed as fractions
