the question I need to answer is below. I already can do equally divided, need some tutoring on below figures.

Suppose Fred and Maria are going to divide a cake using the divider-chooser method. However, Fred is only entitled to 30% of the cake, and Maria is entitled to 70% of the cake (maybe it was a $10 cake, and Fred put in $3 and Maria put in $7).Adapt the divider-choose method to allow them to divide the cake fairly.Assume (as we have throughout this chapter) that different parts of the cake may have different values to Fred and Maria, and that they don't communicate their preferences/values with each other.

Clearly convey your method.

Your goal is to come up with a method of fair division, meaning that although the participants may not receive equal shares, they should beguaranteedtheir fair share. Your method needs to be designed so that each person will always be guaranteed a share that they value as being worth at least as much as they're entitled to.
