The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.
Since the sum of two rational numbers is rational, the answer will be the same as for the sum of an irrational and a single rational number. It is always irrational.
They are always rational.
Yes, it is.
Yes, it is.
The sum of two rational numbers is rational.From there, it follows that the sum of a finite set of rational numbers is also rational.
The sum of any finite set of rational numbers is a rational number.
Such a sum is always rational.
Because both of those numbers are rational. The sum of any two rational numbers is rational.
No - the sum of any two rational numbers is still rational:
Since the sum of two rational numbers is rational, the answer will be the same as for the sum of an irrational and a single rational number. It is always irrational.
They are always rational.
Yes, it is.
Yes, it is.
Yes, Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
You can not add irrational numbers. You can round off irrational numbers and then add them but in the process of rounding off the numbers, you make them rational. Then the sum becomes rational.
Yes.
