Question

При разгрузке машины первый грузчик перенес 5 мешков с крупой по 8килограммов каждый,а второй 6 таких же мешка.После этого им осталось перенести ещё 4 таких же мешка.Сколько килог.крупы было в машине.Решить разными способами задачу.

Answer 1

1. 5×8=40(кг)-перенёс 1-ый грузчик
2. 6×8=48(кг)-перенёс другой грузчик
3. 4×8=32(кг)-осталось перенести
4. 40+48+32=120(кг)-было в машине

Answer 2

1 способ 
(5+6+4)*8=120кг крупы было в машине
2 способ
5+6+4=15 мешков всего
15*8=120кг- крупы было в машине
3 способ
5*8=40 кг-первый грузчик
6*8=48 кг-второй грузчик
4*8=32 кг-осталось в машине
40+48+32=120 кг-крупы было в машине
4 способ
(5*8)+(6*8)+(4*8)=120 кг- крупы было в машине

Answer 3

Problem Analysis

We are given that the first loader carried 5 bags of groats, each weighing 8 kilograms, and the second loader carried 6 bags of groats of the same weight. After this, they had to carry 4 more bags of the same weight. We need to determine the total weight of groats in the truck.

Solution 1: Using Addition

We can solve this problem by adding up the weights of the bags carried by each loader and the remaining bags.

The first loader carried 5 bags, each weighing 8 kilograms, so the total weight carried by the first loader is 5 * 8 = 40 kilograms.

The second loader carried 6 bags, each weighing 8 kilograms, so the total weight carried by the second loader is 6 * 8 = 48 kilograms.

The remaining bags weigh the same as the bags carried by the loaders, so the weight of the remaining bags is 4 * 8 = 32 kilograms.

To find the total weight of groats in the truck, we add up the weights: 40 + 48 + 32 = 120 kilograms.

Therefore, there were 120 kilograms of groats in the truck.

Solution 2: Using Multiplication

We can also solve this problem by using multiplication.

The first loader carried 5 bags, each weighing 8 kilograms, so the total weight carried by the first loader is 5 * 8 = 40 kilograms.

The second loader carried 6 bags, each weighing 8 kilograms, so the total weight carried by the second loader is 6 * 8 = 48 kilograms.

The remaining bags weigh the same as the bags carried by the loaders, so the weight of the remaining bags is 4 * 8 = 32 kilograms.

To find the total weight of groats in the truck, we can multiply the number of bags by the weight of each bag and then add the weights together: (5 + 6 + 4) * 8 = 15 * 8 = 120 kilograms.

Therefore, there were 120 kilograms of groats in the truck.

Solution 3: Using Subtraction

We can also solve this problem by using subtraction.

The first loader carried 5 bags, each weighing 8 kilograms, so the total weight carried by the first loader is 5 * 8 = 40 kilograms.

The second loader carried 6 bags, each weighing 8 kilograms, so the total weight carried by the second loader is 6 * 8 = 48 kilograms.

The remaining bags weigh the same as the bags carried by the loaders, so the weight of the remaining bags is 4 * 8 = 32 kilograms.

To find the total weight of groats in the truck, we can subtract the weight of the remaining bags from the total weight carried by the loaders: (40 + 48) - 32 = 88 - 32 = 56 kilograms.

Therefore, there were 56 kilograms of groats in the truck.

Conclusion

Using different methods, we have determined that there were either 120 kilograms, 56 kilograms, or 120 kilograms of groats in the truck, depending on the method used to solve the problem.
