Question

Хозяйка планировала законсервировать на зиму 28 кг помидоров. Сначала она законсервировала 18 кг помидоров в 9 одинаковых банках, а затем ещё 3 такие банки. Нужно ли хозяйке ещё консервировать помидоры? Если да, то сколько килограммов?

Answer 1

1)18:9=2(кг)-помидоров в одной банке
2)3*2=6(кг)-помидоров законсервировала позже
3)18+6=24(кг)-законсервировала всего
4)28-24=4(кг)-нужно ещё законсервировать

Answer 2

Да,нужно законсервировать еще 4 килограмма тк
18кг:9банок=2 кг в одну такую банку 
3 банки *на 2 кг=6кг
18кг+6кг=24кг
28-24=4кг

Answer 3

Problem Analysis

The problem states that the owner planned to preserve 28 kg of tomatoes for the winter. She first preserved 18 kg of tomatoes in 9 identical jars, and then an additional 3 jars of the same size. We need to determine if the owner needs to preserve more tomatoes, and if so, how many kilograms.

Solution

To solve this problem, we need to calculate the total amount of tomatoes preserved so far and compare it to the desired amount of 28 kg. If the total amount is less than 28 kg, the owner needs to preserve more tomatoes.

Let's calculate the total amount of tomatoes preserved so far:

1. The owner preserved 18 kg of tomatoes in 9 identical jars. Therefore, each jar contains 18 kg / 9 jars = 2 kg of tomatoes per jar. 2. The owner preserved an additional 3 jars of the same size. Therefore, the total amount of tomatoes preserved in these 3 jars is 3 jars * 2 kg/jar = 6 kg.

The total amount of tomatoes preserved so far is 18 kg + 6 kg = 24 kg.

Now, let's compare the total amount of tomatoes preserved (24 kg) to the desired amount of 28 kg:

- If the total amount of tomatoes preserved is less than 28 kg, the owner needs to preserve more tomatoes. - If the total amount of tomatoes preserved is equal to or greater than 28 kg, the owner does not need to preserve more tomatoes.

In this case, the total amount of tomatoes preserved (24 kg) is less than 28 kg. Therefore, the owner needs to preserve more tomatoes.

To determine how many kilograms of tomatoes the owner needs to preserve, we subtract the total amount of tomatoes preserved (24 kg) from the desired amount (28 kg):

28 kg - 24 kg = 4 kg

Therefore, the owner needs to preserve an additional 4 kg of tomatoes.

Answer

The owner needs to preserve an additional 4 kg of tomatoes.
