Question

1)В двух одинаковых пакетах 4 кг муки.Сколько килограммов муки в пяти таких пакетах?Схематический рисунок и решение задачи.2)Сколько потребуется пакетов,чтобы расфасовать таким же способом 18 кг муки?

Answer 1

4:2=2кг в каждом пакете, т к пакеты одинаковые 
2кг умножаем на 5 пакетов = 10 кг
Для расфасовки 18 кг потребуется 9 пакетов так как 18:2=9 пакетов

Answer 2

1)
4:2=2 кг - муки в одном пакете
5•2=10 кг - муки в пяти пакетах
2) 18:2=9 п - потребуется для расфасовки 18 кг муки
Ответ: 10 кг, 9 пакетов.

Answer 3

Problem 1: В двух одинаковых пакетах 4 кг муки. Сколько килограммов муки в пяти таких пакетах?

To solve this problem, we need to find out how many kilograms of flour are in five identical packages if each package contains 4 kilograms of flour.

Let's break down the problem step by step:

1. Each package contains 4 kilograms of flour. 2. We need to find out the total weight of flour in five such packages.

Solution: To find the total weight of flour in five identical packages, we can multiply the weight of one package (4 kilograms) by the number of packages (5).

The calculation is as follows: 4 kilograms/package * 5 packages = 20 kilograms

Therefore, there are 20 kilograms of flour in five identical packages.

Problem 2: Сколько потребуется пакетов, чтобы расфасовать таким же способом 18 кг муки?

To solve this problem, we need to determine how many packages are required to pack 18 kilograms of flour using the same method as in the previous problem.

Let's break down the problem step by step:

1. We have 18 kilograms of flour. 2. We need to find out the number of packages required to pack this amount of flour.

Solution: To find the number of packages required, we can divide the total weight of flour (18 kilograms) by the weight of one package (4 kilograms).

The calculation is as follows: 18 kilograms / 4 kilograms/package = 4.5 packages

Since we cannot have a fraction of a package, we need to round up to the nearest whole number. Therefore, we would need 5 packages to pack 18 kilograms of flour using the same method.
