Must the opposite of a rational number be a rational number?
No. A rational number is one that may be represented as a simple multiple, or a division. Such as one times seven, or three times seven; OR one divided by seven, or three divided by seven. Or similar.A rational number, if a fraction, when multiplied by the divisor of the fraction, will give a simple whole number. e.g. 7/5, when multiplied by 5 becomes the whole number 7.An irrational number is one that cannot be formed by a simple ratio, or a simple division. e and pi are a couple of common irrational numbers. [irrational demonstrates where the name comes from.]No number can be found which will convert them, by multiplication, into a whole number.
Is the number seven irrational?
No.
Is seven eighths a rational number?
yes it is. technically, a rational number is any number that can be written as a fraction, as in a/b where a and b are both integers. so, seven eights, being a fraction, is, obviously, a rational number. An irrational number is any number that cannot be written as a fraction, such as pi. Remember repeating decimals are rational because they can be written as fractions (1/3). (integer is any whole number and its opposites: ...-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5... )
Is the square root of seven a rational number?
No.
How is thirty seven a rational number?
37 can be written as 37/1 which is a number of the from a/b where a and b are integers. This shows it is rational.
Is negative seven a rational number?
Yes.
Is seven squared an example of an irrational number?
No because 7 squared equals 49 which is a rational number but the square root of 7 is an irrational number
Is six over seven a rational or irrational number?

Is negative six point seven a rational number?
Yes, it is.

Is the square root of seven a real number?
Well, first let's define a "real number." A real number is any number that's not imaginary. It can be rational or irrational. The square root of 7 is 2.64575131... and it goes on forever. This means it cannot be written as a simple fraction. We can give an estimate of the square root of 7 in a fraction form, but this is not the exact result. So, the square root of 7 is a irrational number.Since a real number can be irrational or rational, yes, the square root of 7 is a real number.
Is seven eighths a rational number?
