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))

(a)/(b) = (c)/(d) = (e)/(f) = k(a, b, c, d, e, f gt 0) then

If (a)/(b) = (c )/(d ) = (e )/(f) = (3)/(4) , what is the value of (a+c +e )/( b+d +f) ?
