If it can't be expressed as a fraction then it is an irrational number
No. A rational number is a number that either terminates or repeats. An irrational number neither terminates nor repeats. Therefore, it cannot be both.
No, they are two separate groups of numbers. A number is either rational or irrational, never both.
The product of an irrational number and a rational number, both nonzero, is always irrational
No. No irrational numbers are whole, and all whole numbers are rational.
Integers are rational. In the set of real numbers, every number is either rational or irrational; a number can't be both or neither.
No number can be both rational and irrational. And, at the level that you must be for you to need to ask that question, a number must be either rational or irrational (ie not neither). 0.555555 is rational.
If it can't be expressed as a fraction then it is an irrational number
Integers and fractions that have integers in the numerator and denominator are rational. A number can't be rational and irrational at the same time - irrational means "not rational".
0.727272 is the ratio of 727,272 and 1,000,000. So it's nice and rational.
If it ends there, it is rational. If the "68" continues on and on, it is also rational.
Irrational* * * * *No.The number can be represented by a terminating decimal so it is rational.A number cannot be both rational and irrational. And unless you are into higher maths (and if you are, the distinction between rationals and irrationals will be child's play) there are none that are neither rational nor irrational. So, for your purposes, they must be one or the other but cannot be both.Even if it is an infinite decimal, with 6868 going on for ever, it is rational.
No, no number can be both rational and irrational.
No. A rational number is a number that either terminates or repeats. An irrational number neither terminates nor repeats. Therefore, it cannot be both.
It will be irrational.
It doesn't happen. A number cannot be both rational and irrational. It is possible for it to be NEITHER if it is not Real number, i.e. involves the square root of -1, i.e is an imaginary or complex number number.
It can't be both at the same time. Irrational means "not rational".
