Writing it on a cheque

On a cheque the amount line reads "Four thousand one hundred and twenty and 00/100" — or "Four thousand one hundred and twenty only" in Indian and much of Commonwealth practice. The fraction or the word "only" exists to stop anyone appending digits after what you wrote. Draw a line through any space left over for the same reason.
