A biscuit recipe for 10 servings uses 225 grams of sugar. How much sugar is needed for 4 servings if the recipe is reduced without changing its proportions?

Объяснение

The smaller batch is 4 divided by 10, or 0.4, of the original, so it needs 225 times 0.4, which is 90 grams. Using 219 grams by subtracting the six fewer servings barely changes the ingredient and does not preserve the amount per serving.
