A rational number is one that can be written as a simple fraction, with integers in the numerator and denominator. A number that can't be written this way is irrational.Also, a rational number, when calculated as a decimal, will either terminate (for example, 1/4 = 0.25), or it will repeat a certain digit or group of digits over and over, after a certain point (for example, 1/6 = 0.16666666...)

it is rational because it is terminating

All rational numbers are real numbers.
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
All prime numbers are rational.
