Answer:
38. -2.2
39. -1
Step-by-step explanation:

First let's count how far C is from F.
5 - (-4)=5 + 4 = 9
There are 9 spaces between C and F.
Let's find 9/5, which is 1.8
Because we're finding the distance from C to F, we add 1.8 to the value C.
-4 + 1.8 = -2.2
The point X in CF that is 1/5 of the distance from C to F is -2.2
Note: It's your judgement on whether or not your professor would want this in decimal form or rounded to -2. I'd keep it as -2.2 if you're not sure, because that is the correct answer.

Now let's do the same thing with BD.
How far is B from D? 1 - (-5) = 1 + 5 = 6
What's (6*2)/3? 12/3 = 4
What's B + 4? -5 + 4 = -1
The point X on BD that is 2/3 of the distance from B to D. is -1
