An irrational number cannot be written as a fraction or a whole number,
Like Pi for example
Yes 9 times pi is an irrational number because it can't be expressed as a fraction
-9 is a rational number
No. 9/46 is an irrational number as it has no definite end.
The square root of 9 is rational.
0.4444
Yes 9 times pi is an irrational number because it can't be expressed as a fraction
No, 9 plus pi is not a rational number. While 9 is a rational number, since it can be expressed as a fraction (9/1), pi is an irrational number, meaning it cannot be expressed as a fraction of two integers. The sum of a rational number and an irrational number is always irrational, so 9 plus pi remains irrational.
9 is a rational number
What is 'pie' ; the meat pie that you eat??? I think you mean 'pi' , the mathematical symbol. Please spell it correctly.!!!!! pi = 3.141592654.... is an irrational number. Casually, an IRRATIONAL number is one which the decimals go to infinity and the decimal digits are not in any regular order. Any number rattional or irrational multiplied to aN IRRATIONAL number produces an irrational result. Hen ce -9 is rational -9(3.141592654...) = -28.27433388... is irrational.
-9 is a rational number
No, it is rational.
No.

The number has a decimal representation that terminates (after 9 digits). If it terminates, the number is rational.
It is a whole number so it is rational.
No. 9/46 is an irrational number as it has no definite end.
No.
