9 out of 7 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are integers, and the denominator is not zero. In this case, 9/7 can be simplified to 1.28571428571, which is a rational number.
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, ( \frac{7}{9} ) is not irrational; it is a rational number. A rational number is defined as any number that can be expressed as the quotient of two integers, where the denominator is not zero. Since 7 and 9 are both integers, and 9 is not zero, ( \frac{7}{9} ) is a rational number.
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
It is a rational number as 9

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.
