Prove the sum of any two rational numbers is rationalTake two integers, r and s.
We can write r as a/b for integers a and b since a rational number can be written as a quotient of integers
We can write s as c/d for integers c and d since a rational number can be written as a quotient of integers
Add r and s:
r + s = a/b + c/d
With a common denominator bd, we have:
r + s = (ad + bc)/bd
Because a, b, c, and d are integers, ad + bc is an integer since rational numbers are closed under addition and multiplication.
Since b and d are non-zero integers, bd is a non-zero integer.
Since we have the quotient of 2 integers, r + s is a rational number.

X is such that X belongs to rational numbers and X is less than or equal to 1 and greater than 0X is such that X belongs to rational numbers and X is less than or equal to 1 and greater than 0
Greater than 0 means we don't include 0
0 <
less than or equal to 1 means we include 1:
[B]0 < x <= 1[/B]
