Question

Реши задачу вычисли и запиши ответ В ПЕРВЫЙ ДЕНЬ СОБРАЛИ 80 КИЛОГРАММ ВИНОГРАДА ЧТО В 2 РАЗА БОЛЬШЕ ЧЕМ ВО ВТОРОЙ ИЗ ВСЕГО ВИНОГРАДА СДЕЛАЛИ ИЗЮМ СКОЛЬКО КИЛОГРАММОВ ИЗЮМА ПОЛУЧИЛОСЬ ЕСЛИ ЕГО МАССА СОСТАВЛЯЕТ ОДНУ ЧЕТВЁРТУЮ ЧАСТЬ МАССЫ ВСЕГО ВИНОГРАДА

Answer 1

Раз во 2 день собрали в 2 раза больше, значит в 1 день собрали 80/2=40 кг. Тогда всего винограда 80+40=120 кг. Чтобы узнать, сколько изюма, разделим виноград на 4 части 120/4=30 и возьмем 1 часть, т.е. 30 кг

Answer 2

Task Solution

To solve the given problem, we need to calculate the amount of raisins obtained from the grapes and express it as a fraction of the total grape weight.

Let's calculate the amount of raisins obtained from the grapes.

1. Calculate the Weight of Grapes on the Second Day: - Let's assume the weight of grapes on the second day is represented by x kilograms. - According to the problem, the weight of grapes on the first day is 80 kilograms, which is 2 times more than the weight on the second day. - Therefore, the weight of grapes on the second day can be calculated as: 80 / 2 = 40 kilograms.

2. Calculate the Weight of Raisins Obtained: - The weight of raisins obtained can be calculated as a fraction of the total grape weight. - As per the problem, the weight of raisins obtained is one-fourth of the total grape weight. - Therefore, the weight of raisins obtained from the grapes is: 40 / 4 = 10 kilograms.

3. Express the Weight of Raisins as a Fraction of the Total Grape Weight: - The weight of raisins obtained (10 kilograms) can be expressed as a fraction of the total grape weight (80 kilograms). - Therefore, the weight of raisins obtained as a fraction of the total grape weight is: 10 / 80 = 1/8.

So, the amount of raisins obtained from the grapes is 10 kilograms, which is one-eighth of the total grape weight.

Conclusion

The amount of raisins obtained from the grapes, expressed as a fraction of the total grape weight, is 1/8.
