How can car wheels with 7 spokes work out equally while 7 won't go into 360 degress equally?

Question

A circle with an inside diameter equally divisible by seven, such as 21" or 35", will work out perfectly; however, if you divide 360 degress by seven, it never comes out exact, there is always a fraction.

Answer 1

There will be equal fractions. Anything can be divided equally. But not by using whole numbers. Fractions work in all situations.
