Justify why a/b x b/c x c/d x d/ e is equal to a/e when b, c,d, and e are not zero?

lets rewrite the equation so as to better understand why this equation is true..


If both the numerator and the denominator are the same in a fraction, then that fraction is equivalent to 1. So we can rewrite the equation as such.



Since the b's, c's and d's cancel out, a/b*b/c*c/d*d/e=a/e
