The square root of 2 is real number but it is not rational number because it can't be expressed as a fraction.
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
Decimals are real. They can be rational or irrational.
1/2, 5, pi, respectively
Real number, Rational Number
a real number is a number that can be rational or irrational
No. All rational numbers are real. Rational numbers are numbers that can be written as a fraction.
The set of rational numbers is a subset of the set of real numbers. That means that every rational number is a real number, but not every real number is rational. The square root of 2 is an example of a real number that isn't rational; that is, it can't be expressed as the quotient of two integers.
One-eighth
the square root of 2
pi, or the square root of 2.
Not necessarily. All rational numbers are real, not all real numbers are rational.
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
A real number dosen't have to be a rational number as a real number can be rational or irrational i.e the root of 2 is irrational and real. So is (pi).
Decimals are real. They can be rational or irrational.
A real number which is not a rational number is an irrational number.
Yes it is, but not every real number is a rational number
yes example pi which is ratio of circumference of a circle by diameter. That is a real number which is APPROXIMATED as 22/7 but is not a rational number. Another example square root of 5,6,7. These are all real numbers but cannot be expressed as a rational number (p/q form)
