Question

Учащиеся собирали шиповник 3 дня. в первый день они собрали 40% всего шиповника, во второй день 1/3 оставшегося, а в третий день оставшиеся 8кг. Сколько всего шиповника собрали учащиеся.

Answer 1

8кг = 2/3
12 кг = 2 и 3 день
12 кг = 60%
20 кг всего

Answer 2

3/3-1/3=2/3 это 8 кг
8/2*3=12 кг за 2 и 3 день
100-40=60% - это 12 кг
12*100/60=20 кг всего шиповника собрали учащиеся

Answer 3

Problem Analysis

The problem states that students collected rose hips (шиповник) over the course of three days. On the first day, they collected 40% of the total rose hips. On the second day, they collected 1/3 of the remaining rose hips. On the third day, they collected the remaining 8 kg of rose hips. We need to determine the total amount of rose hips collected by the students.

Solution

Let's assume the total amount of rose hips collected by the students is x kg.

On the first day, they collected 40% of the total rose hips, which is 0.4x kg.

On the second day, they collected 1/3 of the remaining rose hips. Since they collected 40% on the first day, the remaining rose hips would be 60% of the total. Therefore, they collected (1/3) * 0.6x kg on the second day, which is 0.2x kg.

On the third day, they collected the remaining 8 kg of rose hips.

To find the total amount of rose hips collected, we can add up the amounts collected on each day:

0.4x kg + 0.2x kg + 8 kg = x kg

Simplifying the equation, we have:

0.6x kg + 8 kg = x kg

Rearranging the equation, we get:

x kg - 0.6x kg = 8 kg

0.4x kg = 8 kg

Dividing both sides of the equation by 0.4, we find:

x kg = 8 kg / 0.4

x kg = 20 kg

Therefore, the students collected a total of 20 kg of rose hips.

Answer

The students collected a total of 20 kg of rose hips.
