Answer 1

Пошаговое объяснение:

2 кг - 8/9 ч

Х кг - 1 ч

Х=2×1:8/9=2×9/8=9/4 =2 1/4 =2,25 кг всего в отделе

2,25-2=0,25 кг насыпали во второй пакет

2-0,25=1,75 кг

ВО второй пакет насыпали на 1,75 кг меньше, чем в первый

Answer 2

Problem Analysis

We are given that a seller has put 2 kg of rice in one package, which represents 8/9 of the total quantity of rice in the department. We need to find the total quantity of rice in the department and determine how much less rice was put in the second package compared to the first.

Solution

Let's assume the total quantity of rice in the department is x kg.

According to the given information, 2 kg of rice represents 8/9 of the total quantity. We can set up the following equation:

2 kg = (8/9) * x kg

To find x, we can solve this equation.

Calculation

To solve the equation, we can multiply both sides by 9/8 to isolate x:

(9/8) * 2 kg = x kg

Simplifying the equation:

2.25 kg = x kg

Therefore, the total quantity of rice in the department is 2.25 kg.

Now, let's find out how much less rice was put in the second package compared to the first.

The first package contains 2 kg of rice. To find the amount of rice in the second package, we subtract the amount put in the first package from the total quantity:

Amount of rice in the second package = Total quantity - Amount in the first package Amount of rice in the second package = 2.25 kg - 2 kg

Calculating the difference:

Amount of rice in the second package = 0.25 kg

Therefore, the second package contains 0.25 kg less rice than the first package.

Answer

The total quantity of rice in the department is 2.25 kg. The second package contains 0.25 kg less rice than the first package.
