Is a rational number times a irrational number?
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Is a square root always an irrational number?
No; the square root of any rational number squared is that rational number. Examples: √(2^2) = √4 = 2. √((1/2)^2) = √(1/4) = 1/2
Which number produces a rational number 1/2?
0.5
What number produces a rational number when multiplied by?
1/5
Why is square root of 0.04 a rational number?
Because it can be expressed as a fraction as 1/5
Is 2 a rational number or irrational?
It is rational. It is a whole number so it cannot be irrational.
Is every rational number a natural number?
No. 1/2 is a rational number but it is not a natural number.
Is the sum of two rational numbers a natural number?
Sum of two rational numbers might be a natural number (1/2 + 1/2), but mostly it's just another rational number (1/2 + 1/3). So answer is no.
Is 9.6 divided by 2 a rational number?
4.8
Is a rational number times a irrational number?
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Is a half a rational number?
Yes 1/2 is a rational number
How do you write 1 as a rational number?
Answer: 1 already is a rational number. If you want to get technical, you could write it as 1/1. Answer: Any integer is a rational number. No matter how you write it, it will still be a rational number. Answer: 10/10, 2/2, 3/3, 365/365, etc.
Is one half a rational or irrational number?
As a number which can be expressed as a fraction, 1/2 is a rational number.
Is a square root always an irrational number?
No; the square root of any rational number squared is that rational number. Examples: √(2^2) = √4 = 2. √((1/2)^2) = √(1/4) = 1/2
A short note on square root of rational number?
Square root of a rational number may either be rational or irrational. For example 1/4 is a rational number whose square root is 1/2. Similarly, 4 is 4/1 which is rational and the square root is 2 which of course is also rational. However, 1/2 and 2 are rational, but their square roots are irrational. We can say the square root of a rational number is always a real number. We can also say the rational numbers whose square roots are also rational are perfect squares or fractions involving perfect squares.
