Male, brown hair, white shirt: Our ratio of computers to support engineers is about 150. Each engineer can look after 150 computers and if we bring on a customer with 300 users, that tells us that ...

A systematic method for obtaining the best possible approximation of a given ratio makes use of some of the properties of continued fractions. Although the procedure involved is more lengthy than ...

The semi-graphical approach is also based on continued fractions. After expanding a ratio such as 0.8639, any two consecutive convergents (say 146/169 and 895/1036) are chosen to form a fraction of ...
