9/7 is rational. Rational numbers are numbers that can be written as a fraction. Irrational Numbers cannot be expressed as a fraction.
0.777.... = 7/9 which is the ratio of two integers, therefore 0.777... is a rational number.
The number has a decimal representation that terminates (after 9 digits). If it terminates, the number is rational.
an irrarional number is a number that can't be written as a fraction or whole number. -sqrt(9)=-3 This is a whole number so it isn't irrational, just rational
It could be either. For example, √9 is a rational number, whereas √2 is not.
No. 0.9 is rational. It is equal to 9/10.
No because 9+7 = 16 which is a rational number
9 is a rational number
No because 2+7 = 9 which is a rational number
-9 is a rational number
It is a whole number so it is rational.
An irrational number cannot be written as a fraction or a whole number,Like Pi for example
It is an irrational number because it can't be expressed as a proper fraction
0.777.... = 7/9 which is the ratio of two integers, therefore 0.777... is a rational number.
Rational
It is a rational number as 9
-52 is a rational number because it can be expressed as a fraction in the form of -52/1
The number has a decimal representation that terminates (after 9 digits). If it terminates, the number is rational.
