56 is a rational whole natural number.
Or to put it another way:
56 is a Natural number, but as all natural numbers are also whole numbers 56 is also a whole number, but as all whole numbers are also rational numbers 56 is also a rational number.
Natural numbers are a [proper] subset of whole numbers;
Whole numbers are a [proper] subset of rational numbers.
The set of rational numbers along with the set of irrational numbers make up the set of real numbers
-13 is rational and an integer.
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. All natural and whole numbers are rational.
Irrational numbers have infinitely long, non-repeating decimal expansions. They cannot be natural numbers or whole numbers. Those are rational.
The number 12 is a natural number, a whole number, an integer, and a rational number. A natural number is a positive integer starting from 1, which includes 12. Whole numbers include all natural numbers along with zero, so 12 is also a whole number. Integers include all whole numbers along with their negatives, making 12 an integer. Lastly, a rational number is any number that can be expressed as a fraction, and 12 can be written as 12/1, making it a rational number.
No. No irrational numbers are whole, and all whole numbers are rational.
It is rational, whole, integer and real but not natural nor irrational.
3.5 is real, rational, and natural. It's not irrational, integer, or whole.
No. 328143 is not an irrational number. It is a real, rational, whole, and natural number.
-15 is a rational integer whole number
It can be written as a fraction, so it is rational. It is not an integer, whole number or irrational.
The square root of 25 is 5, which is a whole number, an integer, a natural number and a rational number.
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
Rational, whole and integer. Some mathematicians consider it a natural number, others do not.
-13 is rational and an integer.
Since pi is an irrational number, then 3pi will be an irrational also.
Every irrational number is NOT a rational number. For example, sqrt(2) is irrational but not rational. A natural number is a counting number or a whole number, such as 1, 2, 3, etc. A rational number is one that can be expressed as a ratio of two whole numbers, which may be positive or negative. So, -2 is a rational number but not a counting number (it is an integer, though). Also, 2/3 is a rational number but not a whole, counting number or a natural number.
3 is natural number, a whole number, an integer, a terminating decimal, and a rational number. It is not an irrational number.
