One full bread recipe makes 6 servings and uses 270 grams of flour. A baker makes 2.5 times the full recipe. How many grams of flour are used? Enter the number of grams.
Correct answer
675
Explanation
Making 2.5 batches requires multiplying the flour by 2.5, so 270 times 2.5 is 675 grams. Adding 2.5 to 270 would treat a batch multiplier as a mass and would leave the proportions inconsistent with the larger yield.
