No.
-7 is a rational number because it can be expressed as a fraction in the form of -7/1
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.
yes
The square root of 7 is an irrational number, so its decimal expansion never ends and never repeats. Rounded to 3 decimal places it is 2.646.
No.
No. And it is not even an irrational number!
No because 7 squared equals 49 which is a rational number but the square root of 7 is an irrational number

yes. rational numbers are numbers that can be expressed as fractions and so since 6/7 is a fraction, it is a rational 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.
