Question

Три одинаковые коробки конфет и две одинаковые шоколадки весят 1200 г. Сколько весит шоколадка, если коробка конфет весит 300 г?

Answer 1

1). 300*3=900 грамм весят три коробки конфет.
2) 1200 - 900 = 300 грамм весят две шоколадки.
3) 300:2=150 грамм весит одна шоколадка.
Ответ: 150 грамм.

Answer 2

Всего 3 коробки конфет,их цена по 300 г каждая,значит их общий вес=300*3=900г
А вес двух шоколадок тогда будет равен 1200-900=300г.А вес одной шоколадки тогда будет 300:2=150г

Answer 3

Problem Analysis

We are given three identical boxes of candies and two identical chocolates. The total weight of the three boxes of candies and two chocolates is 1200 grams. We need to determine the weight of one chocolate if the weight of one box of candies is 300 grams.

Solution

Let's assume the weight of one chocolate is x grams.

The total weight of the three boxes of candies is 3 * 300 grams = 900 grams.

The total weight of the two chocolates is 2 * x grams = 2x grams.

According to the given information, the total weight of the three boxes of candies and two chocolates is 1200 grams.

Therefore, we can write the equation:

900 grams + 2x grams = 1200 grams

To find the weight of one chocolate, we need to solve this equation for x.

Solving the Equation

Let's solve the equation step by step:

900 grams + 2x grams = 1200 grams

Subtract 900 grams from both sides:

2x grams = 1200 grams - 900 grams

2x grams = 300 grams

Divide both sides by 2:

x grams = 300 grams / 2

x grams = 150 grams

Answer

Therefore, the weight of one chocolate is 150 grams.

Verification

To verify our answer, let's substitute the value of x into the equation:

900 grams + 2 * 150 grams = 1200 grams

900 grams + 300 grams = 1200 grams

1200 grams = 1200 grams

The equation is balanced, which confirms that our answer is correct.

Conclusion

The weight of one chocolate is 150 grams.
