One and a half? That half there must be an indication. It could be 20 per cent or 60 per cent or 50 per cent. It depends on what is half if it is exactly half. Whatever you see is what you write. You must see the number, then you write the 1 on the caratage, then the percentage you will see if it is 50 that is registered you write 50. If it is 60 then you write that.
