Question

В магазин завезли морковь. В первый день продали 2/7 привезённой моркови и еще 80 кг. После этого в магазине осталось 3/7 привезённой моркови. Сколько кг моркови привезли в магазин

Answer 1

Пишем такое уравнение
2/7*Х+ 80 = 3/7*Х (продали и осталось)
Упрощаем
1/7*Х = 80
Целое по его части находим делением.
Х = 80  : (1/7) = 80 * 7 = 560 кг всего - ОТВЕТ

Answer 2

Calculation of Carrots Sold and Remaining

To calculate the amount of carrots brought to the store, we need to analyze the information provided.

According to the information given: - On the first day, 2/7 of the carrots brought to the store were sold, along with an additional 80 kg. - After the first day, 3/7 of the carrots brought to the store remained.

Let's calculate the amount of carrots brought to the store:

1. Calculate the amount of carrots sold on the first day: - 2/7 of the carrots were sold. - Add the additional 80 kg sold on the first day. - Multiply the total by 7/2 to find the original amount of carrots brought to the store.

Calculation: (2/7) * x + 80 = (7/2) * x

To solve this equation, we can multiply both sides by 14 to eliminate the fractions: 14 * [(2/7) * x + 80] = 14 * [(7/2) * x] 4x + 1120 = 49x

Simplifying the equation: 45x = 1120 x = 1120 / 45 x ≈ 24.89

Therefore, approximately 24.89 kg of carrots were brought to the store.

2. Calculate the amount of carrots remaining after the first day: - 3/7 of the carrots brought to the store remained. - Multiply the remaining amount by 7/3 to find the original amount of carrots brought to the store.

Calculation: (3/7) * x = (7/3) * x

To solve this equation, we can multiply both sides by 21 to eliminate the fractions: 21 * [(3/7) * x] = 21 * [(7/3) * x] 9x = 147x

Simplifying the equation: 6x = 147 x = 147 / 6 x ≈ 24.5

Therefore, approximately 24.5 kg of carrots were brought to the store.

Based on the calculations, approximately 24.89 kg or 24.5 kg of carrots were brought to the store.
