Equal shares
A number of people invest different amounts in a project. When it comes to sharing the profits of the project the usual method is that a person who initially invests more capital gets a larger share of the profits and whoever invests less capital receives a smaller share of the profits. That is, the division of profits is directly proportional to the amount of the initial investment.

Direct equal shares

Let x, y and z represent the profits of Anthony, Joseph and Ana. Then we can work out the proportion of profit to  investment.
