Yes.
2 x 3.14 = 6.28
= 6 7/25
= 157/25
which is rational.
If you are using 3.14 as an approximation to {pi}, then 2 x {pi} is not rational.
No, it is not.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
314 ÷ 2 = 157
1 x 314 and 2 x 157
The given whole number of -2 is a rational number
2 is a rational number and it is also a prime number
2 is a rational number and it is also a prime number
It is not. It is the rational number 6.28 = 628/100.
They are 2 and 157.
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.
