Question

Suppose that a waffle recipe designed to feed three people calls for 600 mL of flour. How many milliliters of flour would you use if you wanted to extend the recipe to feed four people?

Answer 1

To adjust the recipe for four people, multiply the original amount of flour by 4/3, resulting in 800 mL of flour. This method of scaling recipes based on the number of servings uses simple proportions, similar to how Devon would calculate the soup needed for 100 guests, leading to 37.5 L of soup.

Step-by-step explanation:

The question is asking how to adjust the amount of flour in a waffle recipe when the number of servings changes. Originally, the recipe calls for 600 mL of flour for three people. To find out how much flour would be needed for four people, you use a simple proportio

Since the number of servings is increasing from three to four, which is a factor of 4/3, you can multiply the original amount of flour by this factor.

600 mL (for 3 people) x 4 (people) / 3 (people) = 800 mL of flour (for 4 people)

This same concept of proportions and unit conversion can be applied in other contexts. For example, if Devon from the catering company needs to make soup for 100 guests and one serving is 375 milliliters, she would need:

375 mL/serving x 100 servings = 37,500 mL,

which can be converted to liters by dividing by 1,000.

37,500 mL / 1,000 = 37.5 L of soup in total.
