Question

Use the associative property to explain why the following statement is true. Any number that has 9 as a factor also has 3 as a factor.

Answer 1

Step-by-step explanation:

Let's suppose 9 is a factor of the number N. That means N is 9 times some integer M.

N = 9xM

Since 9 = 3x3, we can also write N as

N = 3x3xM

That means N is 3 times some integer (3xM). So 3 is also a factor of N.
