YES
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.
-1/9 is rational because it can be expressed as a fraction (ratio).
It is an irrational number because it can't be expressed as a proper fraction
Yes a rational number is one which can be represented by one integer over another (possibly the same) integer which cannot be zero. 1 2/7 = (1×7+2)/7 = 9/7 (as an improper fraction) 9/7 is one integer over another integer, so it is a rational number.
No because it can be expressed as a fraction in the form of 7/9
Any number that can be written as a fraction is rational -- therefore, 4/9 squared is rational (it can still be written as a fraction even if you multiply it by itself).
If you mean 4/9 as a fraction then it is a rational number
Yes. Any rational number divided by another rational number is also rational.
Yes, it is.
Any rational number is a fraction multiple of 1/9. For example, if you want 7/8 thenp/q = (7/8)*(1/9) = 7/72 is the multiple that you want.
5/7 ÷ 7/9 = 5/7 x 9/7 = (5 x 9)/(7 x 7) = 45/49
