Why is it important to look at serving size

Cause it tells you how many you need, it's just like instruction, but there just in serving form like for EXAMPLE : Baking a Cake, Pie, Cupcake of any such it may say sometimes that you may say it up to 54 or 117 servings. See it all depends what u looking at cause the Serving Size is like the amount of food or drink that can be generally served so basically telling you that its just like instruction,

 -_HoPe this has helped you any todayy nd have a nice rest of the day .
