Question

Как с помощью гирь отвесить 1кг? 4кг? 2 кг?, имея гири весом 3кг, 3кг, 5кг,5кг. Подскажите пожалуйста. Смогли решить только с 2 кг.

Answer 1

1 кг. - на одну чашу кладём две гири по 3 кг. всего 6 кг, на вторую - 1 гирю в 5 кг. Недовес на второй чаше равен 6-5=1 кг.
4 кг. - на одну чашу кладём две гири по 3 кг всего 6 кг, на вторую 2 гири по 5 кг. всего 10 кг. Теперь недовес на первой чаше составит 10-6=4 кг.

Answer 2

Using Weights to Measure 1kg, 4kg, and 2kg

To measure 1kg, 4kg, and 2kg using weights of 3kg, 3kg, 5kg, and 5kg, you can follow these steps:

1. Measuring 1kg: To measure 1kg using the given weights, you can use the 3kg and 5kg weights. Here's how: - Place the 3kg weight on one side of the balance scale and the 5kg weight on the other side. - Since the 3kg weight is lighter, add the 5kg weight to the same side as the 3kg weight until the scale balances. This will indicate that the total weight on that side is 1kg.

2. Measuring 4kg: To measure 4kg using the given weights, you can use the 3kg, 3kg, and 5kg weights. Here's how: - Place the 3kg and 5kg weights on one side of the balance scale and the two 3kg weights on the other side. - Since the weights are not balanced, remove one of the 3kg weights from the side with the 3kg and 5kg weights. This will indicate that the total weight on that side is 4kg.

3. Measuring 2kg: To measure 2kg using the given weights, you can use the 3kg and 5kg weights. Here's how: - Place the 3kg weight on one side of the balance scale and the 5kg weight on the other side. - Since the 3kg weight is lighter, add the 3kg weight to the same side as the 3kg weight until the scale balances. This will indicate that the total weight on that side is 2kg.

Conclusion

Using the provided weights of 3kg, 3kg, 5kg, and 5kg, you can measure 1kg, 4kg, and 2kg as described above. If you have any further questions or need additional assistance, feel free to ask!
