<span>( 2 x 4 ) x 7 = 2 x (7 x 4 ) represents the associative property of multiplication. The associative property states of multiplication states, that you can multiply even how the numbers are grouped.
You can test this you're self.
1. Multiply 2*4=8 8 *7=56
2. 7*4=28 28*2=56
In conclusion, </span><span>( 2 x 4 ) x 7 = 2 x (7 x 4 ), uses the associative property of multiplication.
