Problem 6.2. For preparing one portion of salad, 2 cucumbers, 2 tomatoes, 75 grams of feta cheese, and 1 pepper are required. The restaurant's warehouse has 60 peppers, 4.2 kg of feta cheese, 116 tomatoes, and 117 cucumbers. How many portions can be made?
Answer: 56.

Solution. The pepper will last for $60: 1=60$ servings.

The feta cheese will last for $4200: 75=56$ servings (kilograms converted to grams).

The tomatoes will last for $116: 2=58$ servings.

The cucumbers will last for $117: 2=58.5$, i.e., 58 whole servings.

Since all ingredients must be included in each serving, exactly 56 servings can be prepared.
