7)    product f two numbers = -25/3
       one of the number   = 5/12
       let the other number be x
       then ,
            x * 5/12   = -25/3
            x = -25/3 / 5/12
            x = -25/3* 12/5
            x =-300 /15
            x =  -20 
therefore other number is -20

8) sum of 3/7 and -5/7
 3/7+-5/7 = ?
( denominators are same so add directly )
-2/7 is the answer 
........................................................................................................................
10)  subract 2/3 from 3/4
3/4 - 2/3 ( denominators are 4 and 3 so find LCM  of 4 and 3 )
  9 + 8 / 12 = 17/12 is the answer 
.........................................................................................................................
evaluate 3/8 + 5/3 +7/6  (denominators are 8 3 6 lcm of 8,3,6 ) 
  9+40+28 /24 = 77/24 is the answer
