Answer 2

Answer:

positive

Step-by-step explanation:

-9/16= -0.5625

9/8= 1.125

-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)

              =0.5625

  the reason

             + * + = +

              - * - = +                                              

              + * - = -

              +/+ =+

              - / - = -

              -/ + = -

              + / - = -
