Yes, 3.14/2 is a rational number.
3.14/2 = 1.57
1.57 = 1 57/100 = 157/100.
Do not confuse this with pi, which is 3.14159..., which is an irrational number.
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.
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.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
0.4
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.
Yes, it is.
Yes
Yes. 50/2=25. 25 is a full number, therefore it is rational.
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.
