Answer 1

a+(-7/8)=(-3/2)

a=(-3/2)-(-7/8)

a=-3/2+7/8

LCM=8

a=-12/8+7/8

a=-5/8

Answer 2

Answer:

-5/8 should be added

Step-by-step explanation:

let number is to be added is x

one of the number is -7/8

the sum is given as (-3/2)

now we have,

$x + \frac{ - 7}{8} = \frac{ - 3}{2} \\ x = \frac{ - 3}{2} - \frac{ - 7}{8} \\ x = \frac{ - 3}{2} + \frac{7}{8} \\ x = \frac{ - 3 \times 4 + 7 \times 1}{8} \\ x = \frac{ - 12 + 7}{8} \\ x = \frac{ - 5}{8}$

-5/8 should be added to get the required
