A cookie recipe requires combining 400 grams of flour with 500 grams of sugar. If you only have 300 grams of flour available, how much sugar should you use to keep the same ratio?

Explanation

The original ratio of flour to sugar is 400:500, which simplifies to 4:5. To maintain this proportion with 300 grams of flour, set up the ratio 4/5 = 300/x. Solving for x gives x = (300 * 5) / 4 = 375 grams of sugar.
