Tell whether each number is rational?
Rational numbers include integers, and any number you can write as a fraction (with integers in the numerator and denominator). Most numbers that include roots (square roots, cubic roots, etc.) are irrational - if you take the square root of any integer except a perfect square, for example, you'll get an irrational number. Expressions involving pi and e are also usuallyirrational.
How do you write a rational number?
Not too tough . . . Any number that you can completely write down on paperis a rational number.
How do you write 0.2 as a rational number?
0.2 is a rational number in and of itself.
How irrational numbers are different from rational numbers?
A rational number can be expressed exactly by a fraction, with whole numbers in the numerator and denominator; an irrational number is one that can't be written that way. For example, it is easy to prove that you can't write the square root of 2 (or, for that matter, the square root of any natural number that isn't a perfect square), so those numbers are irrational. In the decimal representation, a rational number can have no decimals (e.g., 4), a finite number of decimals (e.g., 3.15), or decimals that eventually repeat over and over again (e.g., 3.12727272727...). An irrational number has an infinite number of decimals, without such a repetition.

You cannot because it is not a perfect square.
Is -8 a rational or irrational number?
rational. The fact that you could write it out in a fraction proves that it is.

6 is a rational number. It can be written as 6/1
What is a square root of a fraction that is rational?
If you are expected to calculate it without a calculator then the first step is to write the fraction as a ratio - a top heavy one if necessary. You will find that the numerator and denominator of the rational fraction are both perfect square numbers. Then the square root of the ratio is the ratio of the square roots.For example, to find the square root of 11.11... recurring.You know that, since it is a recurring decimal, the number is rational.In ratio form, this number is 100/9 and sosqrt(11.11...) = sqrt(100/9) = sqrt(100)/sqrt(9) = 10/3 = 3.33... recurring.
How can you write 721 as a rational number?
