    we need associative property of multiplication which is in the form of a x ( b x c) = (a x b) x c where a,b,c are any real numbers

    hmm assuming that a = 21, b = 7, c = 3x 21 x (7 x 3x) = (21 x 7) x 3x but hmm there's gotta be one not in the parenthesis and that's what is throwing me off.

    A associativve property refers to the changing the order regardless of the parenthesis A is the only one which puts a number out of the brackets i'd go A
