## 'Dividing a Cake' printed from http://nrich.maths.org/

On Annie's ninth birthday her Mum made her a cake which had the figures from $0$ to $9$ round the edge in red icing instead of candles.

Starting from the centre, Annie cut the cake into $3$ pieces with $3$ cuts so that the numbers on each piece added to the same total.

Where were the cuts and what fraction of the whole cake was each piece?
