The phrase "at constant ratios" is correct and usable in written English.
It can be used in contexts involving mathematics, science, or any situation where proportions or relationships between quantities are being discussed.
Example: "The experiment was conducted at constant ratios to ensure accurate results."
Alternatives: "at fixed proportions" or "at stable ratios".
