Question

За один день было собрано 1660кг картофеля. После обеда собрали в 4 раза меньше картофеля,чем до обеда.Сколько килограммов картофеля было собрано до обеда?

Answer 1

Пусть х кг - после обеда, тогда 4х кг - до обеда
получаем
х+4х=1660
5х=1660
х=1660/5
х=332(кг)
4*332=1328(кг)
ответ 1328кг

Answer 2

Calculating the Amount of Potatoes Collected

To calculate the amount of potatoes collected before lunch, we can use the information provided. Let's break it down step by step.

1. Amount of Potatoes Collected Before Lunch: - Total amount of potatoes collected in one day: 1660 kg - Amount of potatoes collected after lunch: 1/4 of the total amount collected in the day

To find the amount of potatoes collected before lunch, we can use the following equation: \[ \text{Potatoes collected before lunch} + \text{Potatoes collected after lunch} = \text{Total potatoes collected in one day} \]

Let's denote the amount of potatoes collected before lunch as \( x \) and the amount collected after lunch as \( \frac{1}{4}x \).

So, the equation becomes: \[ x + \frac{1}{4}x = 1660 \]

Solving for \( x \): \[ \frac{5}{4}x = 1660 \] \[ x = \frac{1660 \times 4}{5} \] \[ x = 1328 \]

Therefore, 1328 kilograms of potatoes were collected before lunch.

This calculation is based on the provided information and the principles of basic algebra.

Conclusion

Based on the given information, 1328 kilograms of potatoes were collected before lunch.
