A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.

Pi is irrational and 3.14159 is rational. So (Pi+3.14159) is irrational. Therefore (Pi+3.14159)/2 is also irrational. It's also halfway between 3.14159 and Pi.

97 divided by 2 is 48.5, which is not an integer. Therefore, 97 is an odd number. Another way to determine if 97 is and even or odd number is simply to look at the last digit in 97. 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.

Recurring decimals such as 0.26262626…, all integers and all finite decimals, such as 0.241, are also rational numbers. Alternatively, an irrational number is any number that is not rational. It is a number that cannot be written as a ratio of two integers (or cannot be expressed as a fraction).

Any mixed number are rational . As mixed number can be written as sum of integer plus proper http://fraction.Eg :2 2/3=2 +2/3 =rational +rational= rational. we also convert mixed number into improper fraction which is of the form of p/q, where p and q€I with q is not equal 0.Eg: 22/3=8/3 which is rational.

22/7 is a rational number. By definition, rational numbers are those that can be expressed as a ratio between two integers. However, 22/7 is also used as a rather crude approximation for pi (the ratio between the circumference and the diameter of a circle), which is an irrational number.

Answer and Explanation: The square root of 100 is a rational number.

Yes, because '2' is the quotient of 2 π, which actually means 2 × π, and π is an irrational number. Then 2π is indeed an irrational number. 2pi is as irrationall as pi.

So 1/2+root 3 = a/b where a and b are irrationals. since rhs is a rational number root 3 should be also rational . ... So our assumption is wrong and hence we conclude that is irrational.

Approximation. But as you can see, 22/7 is not exactly right. In fact π is not equal to the ratio of any two numbers, which makes it an irrational number.

Irrational, then, just means all the numbers that aren't rational. Every integer is a rational number, since each integer n can be written in the form n/1.

Explanation: A rational number is a number, which can be expressed as a fraction. Since 3 can be expressed as 3=31=62=124 and so on, it is a rational number.
