Hi. How do I properly ask someone to give me a ratio of two things? And do I answer them as well?<br/><br/>Question - "Could you give me a ratio of red and blue pens?"<br/><br/>Answer - "The ratio of red and blue pens are 3 to 5"<br/><br/>This is my attempt. Are they appropriate?<br/><br/>And if you replace the <b>to</b> with an <b>in</b> between the two numbers, is it still a ratio then or something else?<br/><br/>E.g. "<b>One in ten</b> workers say they are worried they'll have to continue work indefinitely because they haven't saved enough"<br/><br/>Thank you
