 <span>For lens in S I system,1/v - 1 /u = 1/f 

gives 1/v=1/f + 1/u, 

multiply by 'u' on both sides 

u/v =u/f + 1 

u/v = ( u+f ) / f 

inverting, 

v/u = f / (u+f) 

Therefore magnification 'm' = v/u=f / (u+f) 

'm' = f / (u+f) 

Given magnification is 5 / 9 

f / (u+f) = 5 / 9 

object distance 'u'= 4f /5 

Now substitute for focal length f ( focal length of diverging lens is negative)</span>

You need to add two mixed numerals.
One is positive and one is negative.
To add a positive number and a negative number, first take the absolute value of both, making them both positive. Then subtract the smaller absolute value from the larger absolute value. Finally, the sign of the answer is the same sign as the number that has the larger absolute value.

The numbers are -4 5/8 and 2 1/8

Take absolute values:
|-4 5/8| = 4 5/8
|2 1/8| = 2 1/8

Subtract the smaller absolute value from the larger absolute value.

4 5/8 - 2 1/8 = 2 4/8 = 2 1/2

The greater absolute value is 4 5/8.
Since the number with the larger absolute value was -4 5/8, a negative number, the answer is negative, -2 1/2

-4 5/8 + 2 1/8 = - 2 1/2
