On Monday Dolly, Kapa and Lolo cut a pizza into equal sized pieces and share the pizza in the ratio 4 : 3 : 5. This means that there were 12 pieces and Dolly ate one third, Kapa ate one quarter and Lolo ate five twelfths of the pizza.
On Tuesday they buy a pizza of the same size and share it in the ratio 5 : 4 : 6. Does Dolly get more pizza on Monday or Tuesday?
On Wednesday they decide to share the pizza so that in total they will all have had the same amount. How should it be shared on Wednesday and will they need a protractor to do this?
