 Closure Property: For any two rational numbers a/b and c/d, their sum (a/b+c/d) is also a rational number.
Example: 5/8 + 6/8 = (5+6)/8 = 11/8
 Commutative Property: For any two rational numbers a/b and c/d, (a/b+c/d) = (c/d+a/b), where a, b, c, d are integers and b and d are not equal to zero.
Example: 5/8 + 6/8 = 6/8 + 5/8 = (5+6)/8 = 11/8
 Associative Property: For any three rational numbers a/b, c/d, and e/f, a/b+(c/d+e/f) = (a/b+c/d)+e/f, where a, b, c, d, e, and f are integers, and b, d, and f are not equal to zero.
Example: 5/6 + (7/2 + 8/6) = (5/6 + 7/2) + 8/6 = 20/6
