The property demonstrated in the example 2 + (5 + 6) = (2 + 5) + 6 is The Associative Property.

We can tell this is the associative property because of what the associative property states. The associative property states that it doesn't matter where you put parenthesis when adding or multiplying numbers. Since we see an equation that has addition, and two equations being equal to each other, despite having different placements of parenthesis, we can see that this equation is demonstrating The Associative Property.

Answer:

YES IT IS

Step-by-step explanation:

2-3 + 3.3

= -1 + 3.3

= -4.3

We learn that:

Rational number: rational number is the number that can be written as a/b (a and b would be intergers and b is not equal to 0). Rational number would be most of numbers we use in out life, except Square root and Pi number.

In this case, -4.3 can be write as -43/10

So YES it would be a rational number
