Question

На пост главы администрации города претендовало три кандидата : Журавлёв , Зайцев , Иванов . Во время выборов за Иванова было отдано в 2 раза больше голосов , чем за Журавлёва , а за Зайцева — в 3 раза больше , чем за Журавлёва и Иванова вместе . Сколько процентов голосов было отдано за победителя ?

Answer 1

Пусть  за журавлева отдано х голосов

тогда за иванова - 2*х голосов

за зайцева   (х+2х)*3   голосов  =  9х

 

всего голосов   х+2х+9х = 12 х  голосов

 

 

12х  - 100%

9х    -     ?     решаем пропорцией

 

 

? (ну или там обозначь как-то)  =  9х*100 / 12 х  =  75 %  

 

ответ за аобедителя - Зайцева проголосовало 75% 

 

 

Answer 2

Calculation of Percentage of Votes for the Winner

To calculate the percentage of votes for the winner, we need to determine the total number of votes cast for each candidate and then calculate the percentage of votes received by the candidate who won.

According to the information provided, there were three candidates: Zhuravlev, Zaitsev, and Ivanov. During the elections, Ivanov received twice as many votes as Zhuravlev, and Zaitsev received three times as many votes as Zhuravlev and Ivanov combined.

Let's assign variables to represent the number of votes received by each candidate: - Let's say Zhuravlev received x votes. - Ivanov received 2x votes. - Zaitsev received 3(x + 2x) votes, which simplifies to 9x votes.

To find the total number of votes cast, we need to add up the votes received by each candidate: Total votes = Zhuravlev's votes + Ivanov's votes + Zaitsev's votes Total votes = x + 2x + 9x Total votes = 12x

Now, to calculate the percentage of votes received by the winner (Ivanov), we divide the number of votes received by Ivanov by the total number of votes and multiply by 100: Percentage of votes for the winner = (Ivanov's votes / Total votes) * 100 Percentage of votes for the winner = (2x / 12x) * 100 Percentage of votes for the winner = (2/12) * 100 Percentage of votes for the winner = 16.67%

Therefore, the winner (Ivanov) received approximately 16.67% of the total votes.
