ASSOCIATIVITY The multiplication of rational numbers is associative. That is if `a/b c/d and e/f` are three rational numbers then `(a/b xx a/d) xx e/f = a/b xx (c/d xx e/f)`

ASSOCIATIVITY The multiplication of rational numbers is associative.That is if (a)/(b)(c)/(d) and (e)/(f) and (e)/(f) are three rational numbers then ((a)/(b)xx(a)/(d))xx(e)/(f)=(a)/(b)xx((c)/(d)xx(e)/(f))

ASSOCIATITY The subtraction of rational numbers is not asociative i.e.for any three rational numbers (a)/(b)(c)/(d) and (e)/(f) we have

ASSOCIATIVITY If abc are any whole numbers then (a xx b)xx c=a xx(b xx c)

Property 3 (Associativity): the multiplication of integers is associativie.for any three integers abc we have a xx(b xx c)=(a xx b)xx c

a. b. c. d. e. f. g. h.

Consider the multiplication 999 xx abc = def132 in decimal notation, where a, b, c, d, e and f are digits. What are the values of a, b, c, d, e and f respectively ?

For rational numbers (a)/(b), (c )/(d) and (e )/(f) we have (a)/(b) xx ((c )/(d) +(e )/(f))= ______ + _______.
