Yes.
No, it is always irrational.
A decimal rational number can be expressed as a fraction A decimal irrational number can not be expressed as a fraction
The sum of a rational and an irrational number is always irrational. Here is a brief proof:Let a be a rational number and b be an irrational number, and c = a + b their sum. By way of contradiction, suppose c is also rational. Then we can write b = c - a. But since c and a are both rational, so is their difference, and this means that bis rational as well. But we already said that b is an irrational number. This is a contradiction, and hence the original assumption was false. Namely, the sum c must be an irrational number.
Irrational.
Yes.
There is no number which can be rational and irrational so there is no point in asking "how".
No, it is always irrational.
10.01 is a rational number
-- There's an infinite number of rational numbers. -- There's an infinite number of irrational numbers. -- There are more irrational numbers than rational numbers. -- The difference between the number of irrational numbers and the number of rational numbers is infinite.

is 34.54 and irrational or rational. number
it is a rational number but 4.121314..... is an irrational no
