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

Every integer is also a rational number and a real number.
