It is rational because it can be expressed as the ratio 400040004/10000000000.
A rational number is, by definition, the answer from dividing one integer by another.
Yes, they are.
It is irrational. 133 = 7*17 and so is not the square of any rational number. Therefore its square root cannot be rational.
The set of all rational numbers.If the set contains all of them then no other set can contain any more rational numbers.
No, 1/2 is rational, but not a whole number.
It is rational because it can be expressed as the ratio 400040004/10000000000.
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
It can be written in the form of the ratio 55555/100000.
A rational number is, by definition, the answer from dividing one integer by another.
similarities and differences between ordinary fractions and rational expressions.
It is a rational number because it is a terminating decimal number which can also be expressed as a fraction
Yes, they are.
It is irrational. 133 = 7*17 and so is not the square of any rational number. Therefore its square root cannot be rational.
Any, and every, irrational number will do.
is it rational because there is a pattern
No, by the very definition of rational it can be a fraction with only integers. Common sense would suggest that since irrational means not rational that is impossible.
