Multiplied results of getIngredientPercentage calls in updatePercentageLabels by 100 because they were returning values between 0 and 1. If the specification for those functions is to return values between 0 and 100, then those functions are the ones that are buggy, they should be fixed, and then this change should be reverted. If the specification for those functions is to return values between 0 and 1, then this commit should stay in the code permanently.
