A recipe for 4 people uses 280 grams of flour. How much flour is needed for 10 people when every ingredient is scaled equally?

توضیح

The serving count is multiplied by 10 divided by 4, or 2.5, so the flour must be 280 times 2.5, which is 700 grams. The 286-gram choice merely adds the six extra people to the flour amount and does not keep the recipe proportions.
