Writing it on a cheque

On a cheque the amount line reads "Six hundred and forty-three and 00/100" — or "Six hundred and forty-three 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.
