Let the total votes be 10. Beth received 3 votes, other votes 10-3=7. In order to have received 1/2 of the votes she needed 5 votes so 2 more, which is 2/7 of the other votes.

Answer: B.

At first I got it totally wrong !!

Sum of fractions of the Total votes casted 1.

x+ 3/10=1/2
x=2/10=1/5 ..................... So, beth needs another 1/5 th the total vote casted.

Remaining Fraction = 1- 3/10 = 7/10

Required Fraction = (1/5)/(7/10) = 2/7

.................... Beth .................... Non Beth ................. Total

Initial votes..... \(\frac{3}{10}\) ....................... \(\frac{7}{10}\) ......................... 1 (Assumed)

Requirement...... \(\frac{3}{10} + \frac{2}{10} = \frac{5}{10}\) ..................... \(\frac{7}{10} - \frac{2}{10} = \frac{5}{10}\) ...... 1

\(Fraction = \frac{\frac{2}{10}}{\frac{7}{10}} = \frac{2}{7}\)

Answer = B

Let's assign a "nice" value to the total number of votes cast.
We'll choose a number that works well with the given information.

Let's say that a total of 10 votes were cast.

Beth received 3/10 of the votes cast in a certain election
3/10 of 10 = 3.
So, Beth received 3 votes

What fraction of the OTHER votes cast would she have needed in order to have received 1/2 of the votes cast?
Receiving 1/2 of the votes would require Beth to get a total of 5 votes.
In other words, Beth would have needed 2 additional votes among the 7 people who didn't vote for her

Answer: 2/7 = B

Cheers,
Brent

We can let the total number of votes cast = 100. Thus, Beth received 30 votes, and she must receive 20 of the remaining 70 votes in order to have received 1/2 of the votes cast. Therefore, she must receive 20/70 = 2/7 of the remaining votes.

Answer: B

Let the number of votes cast in the election be 100.

Of these, votes received by Beth = \(\frac{3}{10}\) * 100 = 30.

Therefore, fraction of the other votes cast = \(\frac{7}{10}\) * 100 = 70

If Beth has to receive ½ of the total votes cast, she has to receive 50 votes. So, she needs another 20 votes of the 70 votes.

Therefore, fraction of the other votes cast, needed by Beth = \(\frac{20 }{ 70}\) = \(\frac{2 }{ 7}\).

The correct answer option is B.
