Is 10 rational or irrational?

Answer 1

It is a rational number.

A rational number is any number which can be expressed as a fraction #p/q# where #p and q# are integers and #q# is not equal to zero.
We can write that #10=10/1#. In this fraction both numerator and denominator are natural numbers so #10# is a rational number.
Any natural number (like #2,10,1978# or other) or integer number (natural number or a number opposite to a natural one like #-10,-3# )can be expressed as a fraction with the number in numerator and #1# in denominator. Hence they are all rational numbers.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
