Question

Одно киви весит столько,сколько 3 сливы.На правой чаше весов 2 киви на левой чаши весов одно киви и 5 слив.Находются весы в равновесии?

Answer 1

Нет
2 киви = 6 слив 
 на правой чаши лежит 2 киви = 6 слив
на левой чаши 1 киви = 3 сливы + 5 слив - всего 3+5 = 8 слив
6  меньше 8

Answer 2

Problem Analysis

The problem states that one kiwi weighs the same as three plums. On the right side of the scale, there are two kiwis, and on the left side, there is one kiwi and five plums. We need to determine if the scale is in balance.

Solution

To solve this problem, we need to compare the weights on both sides of the scale. Let's calculate the weight on each side and see if they are equal.

Weight Calculation

According to the problem, one kiwi weighs the same as three plums. Therefore, we can calculate the weight on each side of the scale as follows:

- Right side: 2 kiwis - Left side: 1 kiwi + 5 plums

Since we know that one kiwi weighs the same as three plums, we can convert the weight of the plums on the left side to kiwis. This means that 5 plums are equivalent to 5/3 kiwis.

Now, we can calculate the total weight on each side of the scale:

- Right side: 2 kiwis - Left side: 1 kiwi + 5/3 kiwis = 8/3 kiwis

Comparing the Weights

Now that we have calculated the weights on both sides of the scale, we can compare them to determine if the scale is in balance.

- Right side: 2 kiwis - Left side: 8/3 kiwis

To compare these weights, we can convert the fractions to a common denominator. The common denominator for 2 and 8/3 is 3. Therefore, we can rewrite the weights as follows:

- Right side: 6/3 kiwis - Left side: 8/3 kiwis

Since the weights on both sides are equal (6/3 kiwis = 8/3 kiwis), we can conclude that the scale is in balance.

Conclusion

Based on the calculations, we can determine that the scale is in balance. The weight on the right side of the scale (2 kiwis) is equal to the weight on the left side (1 kiwi + 5 plums). Therefore, the scale is balanced.
