Final answer:
Without additional information such as a recipe or ratio, it is impossible to state how many Stir Fry Sauce pouches are used for #5 Sauce. If such details were provided, a simple calculation could yield the answer.
Step-by-step explanation:
To determine the number of Stir Fry Sauce pouches used for #5 Sauce, we would need additional information such as a recipe or a specific ratio that outlines how many pouches are to be mixed to create the desired amount of #5 Sauce.
In a typical mathematical context, if this was laid out as a direct proportion or a recipe, you could use multiplication or division to calculate the number of pouches needed based on the total volume of #5 Sauce required. For example, if one Stir Fry Sauce pouch is required for every 250ml of #5 Sauce and you need to make 1000ml of #5 Sauce, you would use four pouches (1000ml divided by 250ml per pouch).
