Answer 1

1 часть рапир взял  Фархварсон

по 2 части взяли Гвин иГрейс

1) 1+2+2=5 частей всего

2) 15:5=3 (рапиры) - приходится на одну часть, следовательно профессор взял 3 рапиры

3) 3*2=6 (рапир) - по 6 рапир взял каждый из помощников 

 

Answer 2

Problem Analysis

To solve this problem, we need to determine the number of rapiers each of the travelers took with them to Russia. We know that Gwyn Grace and Farquharson took a total of 15 rapiers with them, and each of Farquharson's assistants took twice as many rapiers as the professor.

Solution

Let's denote the number of rapiers the professor took as x. Then each of Farquharson's assistants took 2x rapiers. Since there are three assistants, the total number of rapiers taken by the assistants is 3 * 2x = 6x. Together with Gwyn Grace and Farquharson, the total number of rapiers is 15.

So, we can set up the equation: x + 6x = 15

Solving for x: 7x = 15 x = 15 / 7

Calculation

Let's calculate the value of x: x = 15 / 7

Result

So, the number of rapiers the professor took with him is 15 / 7, and each of Farquharson's assistants took 2 * (15 / 7) rapiers.

Final Answer

Therefore, the professor took 15 / 7 rapiers, and each of Farquharson's assistants took 30 / 7 rapiers.

Conclusion

The professor took 15 / 7 rapiers, and each of Farquharson's assistants took 30 / 7 rapiers on the journey to Russia.
