Answer 1

Answer:

Hello mate!

Let the no be x,

$x +\frac{3}{4} =\frac{-5}{8}$

$x = \frac{-5}{8}$ $-\frac{3}{4}$

 $= \frac{-5-6}{8}$                  { LCM = 8}

$x = \frac{-11}{8}$.

Answer 2

Sum=-5/8
Let the missing number be x
X+3/4=-5/8
X=-5/8-3/4
Making the denominators equal
-5-6
X=—————=-11/8=-1 3/8
8
Hope you understand it mate
