If someone asked: What is 25% as a ratio
If someone asked: What is 25% as a ratio. What is the correct answer?
Is it 1:3 or 1:4? (Or is it an invalid question?)
Argument:
Ratio Ratio Proportion Percentage
1:3 = 1 to 3 = 1 in 4 = 25%
1:4 = 1 to 4 = 1 in 5 = 20%
Therefore 25% as a ratio is 1:3
Others ague 25% = 25 in 100 = 1 in 4 = 1:4
My understanding is that
A ratio is part-part and expressed as x to y or x:y
A proportion is part-whole and expressed as x in y or x/y (and ":" is not used).
Toss a coin.
We know the probability of heads is 50%
We know the ratio of heads to tails is 50:50 = 1:1 (one head for one tail) = 1 to 1
We know the proportion of heads or tails is 1 in 2.
So 50% as a ratio is 1:1
Following the same logic 25% is 1:3 and not 1:4, else 50% would end up being 1:2 (but 1 in 2 is the proportion and not ratio).
Who is right?
