Is 1 an even or an odd number?
Therefore, 1 is an odd number. Another way to determine if 1 is and even or odd number is simply to look at the last digit in 1. If the last digit is 0, 2, 4, 6, or 8 then the number is even, and if it is 1, 3, 5, 7, or 9 then it is an odd number. The last digit in 1 is 1, therefore, 1 is an odd number.

Yes, 0 is a rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer.
Are all irrational numbers rational?
Irrational numbers are those numbers that are not rational numbers. Irrational numbers can be represented in the decimal form but not in fractions which implies that the irrational numbers cannot be expressed as the ratio of two integers. rational numbers have infinite non-repeating digits after the decimal point.

What is rational number?
A rational number is defined as 'A number which can be written in the form p q where p and q are integers, but q ≠ 0. Some rational numbers become integers, some remain as fractions: Some integers are negative, the rest are whole numbers. Whole numbers include {0,1,2,3,4,5,6,......}. Whole numbers can be broken down into 0 and natural numbers.

Many square roots and cube roots numbers are also irrational, but not all of them. For example, √3 is an irrational number but √4 is a rational number. Because 4 is a perfect square, such as 4 = 2 x 2 and √4 = 2, which is a rational number.
Do irrational numbers obey real numbers?
Since irrational numbers are the subsets of the real numbers, irrational numbers will obey all the properties of the real number system. The following are the properties of irrational numbers: The addition of an irrational number and a rational number gives an irrational number.
Is p irrational or irrational?
Similarly, we can justify the statement discussed in the beginning that if p is a prime number, then √ p is an irrational number. Similarly, it can be proved that for any prime number p, √ p is irrational.
Can irrational numbers be expressed as ratios?
It means that irrational numbers cannot be expressed as the ratio of two numbers. The irrational numbers can be expressed in the form of non-terminating fractions and in different ways. For example, the square roots which are not perfect squares will always result in an irrational number.
Is the sum of two irrational numbers rational or irrational?
Statement: The sum of two irrational numbers is sometimes rational or irrational. Like the product of two irrational numbers, the sum of two irrational numbers will also result in a rational or irrational number. For example, if we add two irrational numbers, say 3√2+ 4√3, a sum is an irrational number.

Properties of irrational numbers 1 The sum of an irrational number and a rational number is irrational. 2 The product of an irrational number and a rational number is irrational, as long as the rational number is not 0. 3 Two irrational numbers may or may not have a least common multiple. 4 Irrational numbers are not closed under addition, subtraction, multiplication, and division. This is in contrast to rational numbers which are closed under all these operations.
