A recurring decimal exists when decimal numbers repeat forever. For example, \(0. \dot{3}\) means 0.333333... - the decimal never ends. Dot notation is used with recurring decimals. The dot above the ...

Even with very limited expertise in mathematics, many of us know that a recurring decimal is one that repeats itself forever. Regretably, we here in Antigua and Barbuda are again faced with a vexing ...

1/3 can be written as 0.33333… (with a string of 3s going on forever) and 4/9 can be written as 0.44444… . We call these recurring decimals. Use a calculator to see what 1/11, 2/11 and 3/11 are as ...

The Mathematical Gazette is the original journal of the Mathematical Association and it is now over a century old. Its readership is a mixture of school teachers, college and university lecturers, ...

THIS is a comprehensive text-book clearly written and well arranged. There is a useful chapter on abridged methods and approximations, and a note (in the appendix) on the metric system. Compound ...
