Description
MellowPriceFeed gets the ratio by doing answer = int256(uint256(ratiosX96[0])) * 1e18 / int256(managedRatiosOracle.Q96());, hardcoding the decimals to 1e18.
However, the decimals are set in the constructor and stored in priceFeedDecimals, and could differ from 1e18.
Recommendation
answer = int256(uint256(ratiosX96[0])) * 10**priceFeedDecimals / int256(managedRatiosOracle.Q96());
