The phrase "a direct ratio" is correct and usable in written English.
It can be used when discussing a relationship between two quantities that are proportional to each other.
Example: "In this experiment, we found that the amount of solution needed is a direct ratio to the concentration of the solute."
Alternatives: "a proportional relationship" or "a straightforward ratio".
