(2 x 4 ) x 7 = 2 x (7 x 4 ) what property does this demonstrate?

Hi There!

( 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, ( 2 x 4 ) x 7 = 2 x (7 x 4 ), uses the associative property of multiplication.

Hope this helps :)

This represents Associative Property.

Where  (a  ×  b) × c = a × (b × c)

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
