Explanation: A rational number is any number which can be expressed as a fraction pq where pandq are integers and q is not equal to zero. In this fraction both numerator and denominator are natural numbers so 10 is a rational number.

Rational Numbers The number 8 is a rational number because it can be written as the fraction 8/1.

4 is not an irrational number because it can be expressed as the quotient of two integers: 4 ÷ 1.

As all natural or whole numbers, including 9 , can also be written as fractions p1 they are all rational numbers. Hence, 9 is a rational number.

Assume that √10 is rational. Therefore √10 = a/b where a and b are coprime integers. Then: √10 = a/b 10 = a^2/b^2 10b^2 = a^2 2*(5b^2) = a^2 Since a^2 is a multiple of 2, a must also be a multiple of 2 (if you square an even number, you get an even number, but if you square an odd number, you get an odd number).

A real number that can NOT be made by dividing two integers (an integer has no fractional part). “Irrational” means “no ratio”, so it isn’t a rational number. Example: π (the famous number “pi”) is an irrational number, as it can not be made by dividing two integers.

An irrational number is a number that cannot be expressed as a fraction for any integers and. . Irrational numbers have decimal expansions that neither terminate nor become periodic.

An Irrational Number is a real number that cannot be written as a simple fraction. Let’s look at what makes a number rational or irrational ……Famous Irrational Numbers.

Yes, because 9/11 is divided as a repeating number.
