Writing it on a cheque

On a cheque the amount line reads "Three thousand eight hundred and forty and 00/100" — or "Three thousand eight hundred and forty 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.
