Yes, the square of any rational number is also a rational number.The square root of 2 is not a rational number.
Yes. Any number that can be written as one integer over a non-zero integer is a rational number. 2 3/5 = (2×5+3)/5 = 13/5 which is the form of one integer over a non-zero integer, thus it is rational.
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.
2/15 is the ratio of 2 to 15 ... precisely the definition of a rational number.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Yes, 1 over 2 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are both integers. In this case, 1 over 2 is the fraction 1/2, which meets the criteria of being a rational number.
Rational
A rational number is one where a whole number is over another whole number. 3 and 2 are both whole numbers so 3/2 is a rational number.
No, it is not.
Yes, 5/2 is a rational number.
If it ends there, it is rational. If it continues with the same digit (2 in this case) over and over, it is also rational.
Yes. 50/2=25. 25 is a full number, therefore it is rational.
Yes, it is.
Yes.
Yes
Yes any number that can be expressed as a fraction is a rational number
Two over three can be expressed as a ratio (2/3), so it is therefore a rational number.
