How to be equal is still a difficult problem, especially when it must be divided equally for a group with a lot of people like 5 or 7 people. But with the method of dividing the bread from two mathematicians from the University of Liverpool, whether it is 5, 7, or 11 parts, there will be a way to divide the bread all the way.
You can try the monohedral disc telling method to cut pizza.
Guide to cutting pizza.
With this method, you can share pizza with any odd number.
According to two mathematicians, this method comes from a long-standing problem, about dividing a circle into equal parts.
"We know there is an answer to this problem, however, we want to give a slightly more beautiful and slightly better answer, instead of dividing it into the usual fan shapes."
This method was published in the report entitled "Infinite Families Of Monohedral Disk Tilings" in 2016.
