use properties of rational numbers to simplify the expression

I'm sorry, but you haven't provided an expression for me to simplify. Could you please provide the expression you want me to simplify?

In order to simplify an expression, we need to apply the properties of rational numbers. Here are a few properties that can be used:

1. Commutative Property of Addition and Multiplication:
a + b = b + a
a * b = b * a

2. Associative Property of Addition and Multiplication:
(a + b) + c = a + (b + c)
(a * b) * c = a * (b * c)

3. Distributive Property:
a * (b + c) = a * b + a * c

4. Identity Element of Addition and Multiplication:
a + 0 = a
a * 1 = a

5. Inverse Element of Addition:
For any number a, there exists a number -a such that a + (-a) = 0.

Using these properties, we can simplify expressions by combining like terms, factoring, canceling out common factors, or applying the distributive property.
