Do you understand?
Which is it. 3x more positive then neg. Or 1/3 votes negative.
1 vote negative and 2 positive votes= 3 total votes with 1 out of 3 voting negative or 1/3. 4 votes positive 2 votes negative= total votes of 6, 2 out of 6 votes for . Which is 33%. Not 25%
Ignoring syntactic of the problem. She wants 1 negtive vote for 3 postive votes. Total votes 4. Ratio 1:4. (25 out of a 100%). 1 out of the 4 is negative. Which is 1 out of 4. Or 1:4
The biggest number is the total number of items in a whole ratio. 1:3 is 1 positive vote and 2 negtive votes. 3:1 is 300% of the object. You have 3 times the amount.
But she wants the smaller portion out of the larger sample. She wants 1 part apples to 3 part oranges. Total apples and orange 4. Total percentage of apples to oranges 75%. Or 1 out 4 is and apple. Or 1:4 is an apple to oranges.
From the wikipedia
Proportions
If the two or more ratio quantities encompass all of the quantities in a particular situation, for example two apples and three oranges in a fruit basket containing no other types of fruit, it could be said that "the whole" contains five parts, made up of two parts apples and three parts oranges. In this case, \tfrac{2}{5}, or 40% of the whole are apples and \tfrac{3}{5}, or 60% of the whole are oranges. This comparison of a specific quantity to "the whole" is sometimes called a proportion. Proportions are sometimes expressed as percentages as demonstrated above.
Now she wants was to do percentage out of a ratio, which is impossible to do. 3 of x, 1 of y.
Wiki again
Number of terms
In general, a ratio of 2:3 means that the amount of the first quantity is \tfrac{2}{3} (two thirds) of the amount of the second quantity. However, a ratio with more than two terms cannot be completely converted into a single fraction; a single fraction represents only one part of the ratio. If the ratio deals with objects or amounts of objects, this is often expressed as "for every two parts of the first quantity there are three parts of the second quantity".
