is a mixed number rational?

The mixed number 1 ½ is also a rational number because we can write it as 3/2. ... This means that natural numbers, whole numbers and integers, like 5, are all part of the set of rational numbers as well because they can be written as fractions, as are mixed numbers like 1 ½.

Let 2+√3 is a rational number. A rational number can be written in the form of p/q. p,q are integers then (p-2q)/q is a rational number. ... Therefore,2+√3 is an irrational number.

The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. ... All natural numbers, whole numbers, and integers are rationals, but not all rational numbers are natural numbers, whole numbers, or integers.

Yes. 2/5 is a rational number. A rational number is a number of the form q/q where p and q are integers and q is not equal to 0. 2/5 is of the form p/q where p is equal to 2 and q is equal to 5.

The number is rational (it's written as a ratio of two integers) but it's also real. All rational numbers are also real numbers. The correct answer is rational and real numbers, because all rational numbers are also real. Incorrect.

Division: Mixed Numbers. A mixed number is a number expressed as the sum of a whole number and a fraction , such as 314 . When you divide a number by a mixed number, first rewrite the mixed number as an improper fractions . Then multiply the number by the reciprocal of the improper fraction.

You can write any rational number as a decimal number but not all decimal numbers are rational numbers. These types of decimal numbers are rational numbers: Decimal numbers that end (or terminate). For example, the fraction 410 can be written as 0,4.

A rational number is any number that can be expressed as the quotient of two integers, that is, it can be expressed as a/b, where both a and b are integers and b does not equal zero; The number 1/4 plainly satisfies the definition of a rational number since its already in the required form of a/b, since both 1 and 4 ...

Mixed numbers are made up of a whole number and a separate fraction. Improper fractions do not show whole numbers separately and the numerator is bigger than the denominator. For example, 3 1 4 (mixed number) is equal to (improper fraction).

Answer and Explanation: No, the difference of two positive rational numbers is not always positive.

it is given that a and b are two positive rational numbers. and we know sum and difference of two rational numbers will give a rational number. hence, a - b is a rational number. so, (√a - √b)(√a + √b) is a rational number.

It is also a rational number. You could argue that the integers are not exactly a subset of the rational numbers, but rather that there is a homomorphism between the set of integers and a subset of the rational numbers, but that is getting pretty involved. It isn't. 23 is both a rational number and an integer.

By definition an irrational number is one that is not rational. Therefore, it is not possible for a number to both rational and irrational. If you're thinking of the number zero (0) then you're mistaken since 0 is clearly rational - it can be expressed as a ratio of whole numbers.

Yes, the difference of two rational numbers is a rational number. The reason for this lies in the following facts: The product of two integers is an...

“Rational” only really applies to real numbers. If we have an imaginary number, then either or or both will not be integers. By this reasoning, imaginary numbers are not rational which may lead you to believe that they must be irrational. ... In a similar way, imaginary numbers are neither rational nor irrational.

Rational Numbers: Any number that can be written in fraction form is a rational number. This includes integers, terminating decimals, and repeating decimals as well as fractions. ... So, any terminating decimal is a rational number.

Let 2+√3 is a rational number. A rational number can be written in the form of p/q. p,q are integers then (p-2q)/q is a rational number. But this contradicts the fact that √3 is an irrational number.
