Is the square root of 25 rational irrational whole natural or integer?
The square root of 25 is 5, which is a whole number, an integer, a natural number and a rational number.
Explain why every natural number is also a rational number but not every rational number is a natural number?
The natural numbers (ℕ) are the counting numbers {1, 2, 3, ...} (though some definitions also include zero: 0) which are whole numbers with no decimal part. Every rational number (ℚ) can be expressed as one integer (p) over another integer (q): p/q where q cannot be 0. The rational numbers can be converted to decimal representation by dividing the top number (p) by the decimal number (q): p/q = p ÷ q. When q = 1, this produces the rational numbers: p/1 = p ÷ 1 = p which is just an integer; it could be one of {[0,] 1, 2, 3, ...} - the natural numbers above: thus all natural numbers are rational numbers. When q = 2, and p = 1, this produces the rational number 1/2 = 1 ÷ 2 = 0.5 which is not one of the natural number above - so some rational numbers are not natural numbers, thus all rational numbers are not natural numbers. Thus ℕ ⊂ ℚ (the set of natural numbers is a proper subset of the set of rational numbers).
Every natural number is an irrational number?
Close. But to make that statement correct, three letters must be deleted:Every natural number is a[n ir]rational number.
Can a rational number be positive?
a rational number is any number that can be expressed as p/q where p and q are both integers. Since integers can most definitely be positive-- you might know them as the set of Natural numbers-- then yes, a rational number can be positive.
Is a natural number always a rational number?
A natural number is always a rational number .
Is every rational number a natural number?
No. 1/2 is a rational number but it is not a natural number.
Is one half a rational number or a natural number?
Rational: yes. Natural: no.
Give you a rational number that is a natural number?
All natural numbers are rational numbers.
Can a natural number be a rational number also?
All natural numbers are rational numbers.
What is the difference between a rational number and a natural number?
a rational number is different from a natural number because a rational number can be expressed as a fraction and natural numbers are just countinq numbers =D
What is a number that is a natural number and an irrational number?
Natural numbers are a part of rational numbers. All the natural numbers can be categorized in rational numbers like 1, 2,3 are also rational numbers.Irrational numbers are those numbers which are not rational and can be repeated as 0.3333333.
Can a number be both rational and natural?
Yes. All natural numbers are rational.
Is every whole number a natural integer and a rational number?
Every whole number is rational and an integer. But the "natural" numbers are definedas the counting numbers, so the negative whole numbers wouldn't qualify.No and yes: it is not a natural number but it is a rational number.
Is 7 rational or irrational?
7 is a rational number because whole numbers, integers, and natural numbers fit under rational and 7 is a natural number:)Yes.
Is a rational number not a natural number?
yes
Is 20 a irrational number?
No, it is a rational number, because all natural numbers are rational.
