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.
No. For example, pi is a real number, but it is irrational (it cannot be converted into an exact fraction).The reverse is true, however: all rational numbers are also real numbers.
1/2, 5, pi, respectively
Decimals are real. They can be rational or irrational.
No. Every real number is not a natural number. Real numbers are a collection of rational and irrational numbers.
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.
the square root of 2
One-eighth
pi, or the square root of 2.
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)
Not necessarily. All rational numbers are real, not all real numbers are 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).
