Final answer:
The weight of the mahi in a citrus grilled entree is related to Mathematics, specifically measurement and proportions. Typically, this information is found in a recipe or on a nutritional menu, where each portion's weight should be clearly stated.
Step-by-step explanation:
The question you've asked about the portion weight of the mahi for a citrus grilled entree seems to refer to determining the weight of a food item in a recipe or a meal, which is generally a question related to measurement in Mathematics. If you are looking for a specific weight as stated in a recipe or a menu, it would typically be provided by the source of the recipe or the restaurant's nutritional information.
The portion size can vary based on the establishment or the recipe. If this is for nutritional information or to understand ratios in a recipe, you would apply mathematical skills such as proportions. An example would be if a recipe calls for a total of 2 pounds of fish to serve 4 people, each portion would weigh 0.5 pounds.
