Akhoth marage and kirui polled 1/4 1/3 and 1/5 respectively of the votes cast in an election what fraction of the votes did
vredina [299]

Answer:

Marage got more votes than akoth by =  1/3 - 1/4 = 1/12

Marage got more votes than kirui by = 1/3 - 1/5 = 2/15

Akoth got more votes than kirui by = 1/4 - 1/5 = 1/20

Step-by-step Explanation:

The share of votes got by Akhoth =  1/4

The share of votes got by Marage =  1/3

The share of votes got by Kirui =  1/5

As

1/4 = 0.5  ⇒  25%

So, Akhoth got  25% votes.

1/3 = 0.33  ⇒  33%

So, Marage got 33% votes.

1.5 = 0.20 ⇒  20%

So,  Kirui got  20% votes.

Determining Comparison:

Marage got more votes than akoth by =  1/3 - 1/4 = 1/12

Marage got more votes than kirui by = 1/3 - 1/5 = 2/15

Akoth got more votes than kirui by = 1/4 - 1/5 = 1/20

Therefore,

A) Marage got more votes than akoth by =  1/3 - 1/4 = 1/12

B) Marage got more votes than kirui by = 1/3 - 1/5 = 2/15

C) Akoth got more votes than kirui by = 1/4 - 1/5 = 1/20
