A cake recipe for 4 servings uses 48 grams of cocoa. How many grams of cocoa are needed for 7 servings with the same recipe proportions? Enter the number of grams.
الإجابة الصحيحة
84
الشرح
The recipe is enlarged by 7 divided by 4, or 1.75, so the cocoa becomes 48 times 1.75, which is 84 grams. Adding the three extra servings to 48 would give 51 grams and would reduce the cocoa available per serving.
