Writing it on a cheque

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