2 is a rational number and it is also a prime number
True.
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
No because -2 is a rational number
Every irrational number is NOT a rational number. For example, sqrt(2) is irrational but not rational. A natural number is a counting number or a whole number, such as 1, 2, 3, etc. A rational number is one that can be expressed as a ratio of two whole numbers, which may be positive or negative. So, -2 is a rational number but not a counting number (it is an integer, though). Also, 2/3 is a rational number but not a whole, counting number or a natural number.
It is rational. It is a whole number so it cannot be irrational.
2 is a rational number and it is also a prime number
what is the rational number for 2/25
Yes, the square of any rational number is also a rational number.The square root of 2 is not a rational number.
No. Though every perfect square is a rational number, not every rational number is a perfect square. Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
True.
No. Any number that has a finite number of digits if RATIONAL.
