Hello! First, let's remember what is Associative Property:
It is a mathematical rule who says that the order of the factors doesn't change the final result of a calculus.
We have the associative property in two mathematical operations, I'll show you some examples:
If we want to sum three numbers, 5, 10 and 15, how is the right way? We have some ways to do it:
(5+10)+15 = (15)+15 = 30
(5+15)+10 = (20)+10 = 30
5+(10+15) = 5+(25) = 30
So, no matter the order of the numbers, we will always get the same result.
An example with the other operation now:
If we want to multiply three numbers, 2, 3 and 5:
(2*3)*5 = (6)*5 = 30
(2*5)*3 = (10)*3 = 30
2*(3*5) = 2*(15) = 30
Also, no matter the order of the factors, we'll always obtain the same result.
However, in the subtraction and in the division we have to follow the right order, according to the precedence, so we can't use the Associative Property on these operations.
Right answer: C and D.
