I think I understand what you are asking but its hard to be sure.
I think its -5 3/4 subracted from 3 1/2
If the question above is the same as you are asking then your answer is -9 1/4
or as a decimal -9.25
No picture, nothing to rate here.
Refer to the figure shown below.

Answer: the predictive value positive of the test is 0.7
Step-by-step explanation:
Given that;
Predicted
Diesease No-Diesease Tt
Actual Diesease 225 75 300
No-Diesease 25 175 200
250 250 500
so finding the predictive value positive of the test,
predictive negative value = (175 / (75+175) )
= 175 / 250
= 0.7
Therefore the predictive value positive of the test is 0.7
