Question

Кофеты разложили в три коробкки в три коробки в 1 3 13\20 КГ ЧТО НА 3/15 КГ МЕНЬШЕ ЧЕМ ВО 2 КОРОБКЕ И НА 13/20 КГ БОЛЬШЕ ЧЕМ В 3 КОРОБКЕ СКОЛЬКО КГ КОНФЕТ ВСЕГО?

Answer 1

10.5 кг
в первой коробке 3,65 кг
во второй 3,65+0.2=3.85
в третьей 3,65-3,65=3

Answer 2

Problem Analysis

We are given that candies are divided into three boxes. The weight of the candies in the first box is 1/3 of the total weight, the weight of the candies in the second box is 13/20 of the total weight, and the weight of the candies in the third box is 3/15 kg less than the weight in the second box. We need to find the total weight of the candies.

Solution

Let's assume the total weight of the candies is x kg.

The weight of the candies in the first box is 1/3 of the total weight, which is (1/3)x kg.

The weight of the candies in the second box is 13/20 of the total weight, which is (13/20)x kg.

The weight of the candies in the third box is 3/15 kg less than the weight in the second box. So, it is ((13/20)x - 3/15) kg.

The total weight of the candies is the sum of the weights in all three boxes: (1/3)x + (13/20)x + ((13/20)x - 3/15) = x

To solve this equation, we can simplify it by finding a common denominator for the fractions: (20/60)x + (39/60)x + ((39/60)x - 4/60) = x

Combining like terms: (98/60)x - (4/60) = x

Multiplying both sides of the equation by 60 to eliminate the denominators: 98x - 4 = 60x

Subtracting 60x from both sides: 38x - 4 = 0

Adding 4 to both sides: 38x = 4

Dividing both sides by 38: x = 4/38

Simplifying the fraction: x = 2/19

Therefore, the total weight of the candies is 2/19 kg.

Answer

The total weight of the candies is 2/19 kg.
