A rational number is a number that can be expressed as a fraction.
This means it can either be a terminating decimal or a recurring decimal.
A terminating decimal is a decimal that doesn't recur (repeat for ever).
A recurring decimal is a decimal that repeats a pattern of numbers after the decimal point.
A good example of this is 1/3. 1/3 = 0.333333.... it is a rational number
13.001001001 is a rational number. Either you meant it to recur or not it makes no difference.
13.001001001 = 13 + 1001001/1000000000 as a terminating decimal
13.001001001....... = 12988/999 as a recurring decimal

When an irrational number is divided by a rational number is the quotient rational or irrational?
Irrational.
What is the product of rational and irrational number?
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
When you multiply an irrational number by a rational number will the answer always be irrational rational or both?
It will be irrational.
Is the product of a rational number and irrational number always rational?
No.A rational times an irrational is never rational. It is always irrational.
What is the Next to rational and irrational number?
Next to any rational number is an irrational number, but next to an irrational number can be either a rational number or an irrational number, but it is infinitely more likely to be an irrational number (as between any two rational numbers are an infinity of irrational numbers).
