----------------------------------
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.
---
Solve for "x":
If amount of compound A is 4x = 255
x = 255/4
------------------------------
Then amt of compound B is 5x = 5(255/4) = 318.75 ml

5B = 255 * 4
Amount of compound B that will be used = , or , or 51 * 4, or 204
Total amount of the drug that will be made = amount of compound A + amount of compound B, or 255 + 204, or mL
