Answer:The equation wth x in the information can be written as 
 1/2 x = 38.5 , Upon solving, the number = 77
Step-by-step explanation:
Let the number Sara was thinking about be x
 halving the number to get an answer = 38.5 can be expressed as 
  1/2 X = 38.5
 The equation with x in the information can be written as 
 1/2 x = 38.5
 solving it becomes 
 1/2 x= 38.5
 x = 38.5 x 2
 x=77
 The number Sara was thinking about = 77
 
        
             
        
        
        
If you would like to order the following values in descending order, you can do this using the following steps:
- 3/4 = - 0.75
1/8 = 0.125
- 0.735
7/8 = 0.875
1/80 = 0.0125
0.056
The result is: 7/8, 1/8, 0.056, 1/80, - 0.735, -0.75.
