Answer 2

Answer:

-2/3

Step-by-step explanation:

product of two rational number = -28 /81

one number  = 14/27

let the second number be x

according to question,

x  *  14/27  = -28 / 81

x  = -28/81   /  14/27

x = -28/81   *  27/14              [ x/y * z/c = x/y  *c/z]

x= -4 *3/9*2                          [after dividing -28 & 14 by 7 , 81 &27 by 9]

x=-12/18                              [ -x * y = -xy]

x=-2/3                                  [ simplifying -12/18 by 6 we get -2/3 ]
