All rationals are real. Rational numbers are numbers that can be written as a fraction. Irrational Numbers cannot be expressed as a fraction.
Not necessarily. All rational numbers are real, not all real numbers are rational.
Yes. -3 is both rational and real. -3 is an integer. All integers are rational numbers. All rational numbers are real numbers. Thus -3 is a rational number and a real number.
It is an integer. All integers are rational but not irrational. All rational and irrational numbers are real numbers.
Rational numbers form a proper subset of real numbers. So all rational numbers are real numbers but all real numbers are not rational.
No. All rational numbers are real. Rational numbers are numbers that can be written as a fraction.

It is an integer. All integers are rational but not irrational. All rational and irrational numbers are real numbers.

No. All rational numbers are real. Rational numbers are numbers that can be written as a fraction.
Rational numbers are a proper subset of real numbers so all rational numbers are real numbers.
It is all of them except an irrational number.
Numbers are split into real and imaginary. Rational numbers are under the category: Real. Therefore all rational numbers are real. An irrational number is also real, but can not be expressed as a fraction.
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. Not all real numbers are rational.
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. Not all real numbers are rational.
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All rational numbers are real.
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.
