Answer 1

let the number to be addes be x
a/q
-5/8 +x= -3/2
(-5+8x)/8=-3/2
=2(-5+8x)= -24
-10+16x = -24
16x= -24+10
16x=-14
x = -14/16
x= -7/8 ans.

Answer 2

The required number is -7/8.

Given:

Sum= -3/2

One number= -5/8

To find:

The other number

Solution:

Let the required number be X.

We know that the sum of X and -5/8 is -3/2.

The equation will be as follows-

X+(-5/8)= -3/2

X-5/8= -3/2

X=5/8-3/2

X=5/8-12/8

X=(5-12)/8

X= -7/8

Therefore, the required number is -7/8.
