    ratio and proportion

    what's the difference between these words, please?
    they seem to be synonyms, according to the dictionary.
    is there any context where these words are not interchangeable?
    thanks.

    I will tell you my understanding of the two words, and I think they are not always interchangeable.

    "ratio" is the relationship between two numbers or amounts, while "proportion" is similar to percentage.


    'He won the election by a 3 to 2 ratio.' (I wouldn't say a '3 to 2 proportion'.)

    'What proportion of your work needs to be done urgently?' (I wouldn't say 'What ratio of your work....?')

    'Proportion' can also be used with the meaning 'amount': I spend a good proportion of my time online.
