But you don't have to do ANY sums at all! Absolutely NO arithmatic whatsoever!
You just take the number - 406 for example - and put a full stop before the last number! 406 becomes 40.6, as in forty-point-six-centimetres....
You don't need to DO anything!
Bit like if I asked you how much 1003 pence is? It's simply £10.03p isn't it? 100pennies in a pound, 1000 penies in 10 pound, etc...
10mm in a cm, 100cm in a metre, etc etc.....
