No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.

Yes - any number with a defined end-point is a rational number.

Any number with a defined end point, including 2.14, is a rational number.

Any number with a defined end-point, such as -0.4744, is rational.

ANY number that has a finite number of digits after the decimal point is rational.
