  2. Meet Mr Dancing Decimal

  3. You know that a decimal point separates a whole number from a decimal fraction of a number. 2 4 Whole Number Fraction of Number

  4. Well, Mr Decimal does a whole lot more. For example, if you want to multiply by ten Mr Dancing Decimal simply dances one step to the right- your right that is… Look And since we can’t leave Mr Dancing Decimal cold and alone at the end of a number we put in a zero to look after him 10 2 4 x 2 4 0 =

  5. You can multiply by a hundred by using dancing decimals Since 100 has two noughts Mr Dancing Decimal jumps twice. And don’t forget the bodyguard! Like this… 4 4 4 0

  6. We haven’t stopped yet! Instead of jumping to the right- he just jumps to the left… Like this We can use Mr DD to divide by 10… 2 4 0 10 - 2 4 0 = And we don’t need the zero anymore
