No it is not.

No.

It is an irrational number and as a decimal number it has no ending

12.52 is rational, as is any number that you can write out completely in decimal form.

No. Not even all the space in the universe would suffice.

A decimal expansion means to write out the base 10 digits of a number. Because irrational numbers do not have a closed form, the decimal expansion will always be an approximation. Consider the irrational number pi, which has the following decimal expansion: 3.14159265... Of course there are more digits to pi than that, which is denoted by the "...". It is sadly impossible to list ALL of the digits of an irrational numbers, since if there were a finite number of digits, you could express it as a fraction, which would not be irrational.

It already is in decimal form.

The number is already in decimal form!

The number in decimal form is 0.12.

This is an irrational number because of it's decimal point... Rational numbers are whole numbers that are divisible by 2 and do not leave a remainder or form a decimal fraction.

This number already is in decimal form.

Suppose an irrational number can be written precisely in decimal form, with n digits after the decimal point. Then if you multiply the decimal value by 10n you will get an integer, say k. Then the decimal representation is equivalent to k/10n, which is a ratio of two integers and so the number, by definition, is rational - not irrational.

It is said to be 22/7. And it is 3.14 in decimal form. * * * * * pi is a transcendental number which is a kind of irrational number. An irrational number cannot be represented as an exact fraction.

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.

no. irrational numbers are always infininately long, otherwise the could be represented as a fraction by multiplying by 10^n and dividing by 10^n where n is a number large enough to make the number a number with no decimals.

Any terminating or repeating decimal number can be converted easily into the form of p/q: a ratio of two integers. If it can be written in that form then it is rational.

4 is a whole number and can never be a decimal.

Such as pi? That would be an irrational number.

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.

An irrational number is one which cannot be expressed in the form of a ratio of two integers. This implies that it cannot be represented by a terminating or recurring decimal number.
