Writing it on a cheque

On a cheque the amount line reads "Two thousand one hundred and fifteen and 00/100" — or "Two thousand one hundred and fifteen 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.
