This article reframes previously identified misconceptions about repeating decimals by describing these misconceptions as limited understandings of how mathematics concepts are referenced. In particular, misconceptions about repeating decimals and th

SummaryRational numbers, except those with denominators of the form 2a5b, have a recurring decimal expansion. It is usual to write these digits from left to right. We give a procedure to write the decimal digits from the opposite end—right to left.

The traditional technique for converting repeating decimals to common fractions can be found in nearly every algebra textbook that has been published, as well as in many precalculus texts. However, students generally encounter repeating decimal numer

Repeating decimals are taught in elementary, junior high and high school. However, they are usually not taught in university mathematics. We should learn the deep theory and some mystery of repeating decimals, and use them for teaching in several sta

In the early eighteenth century, techniques of computation for decimal fractions, especially non-terminating repeating decimals, were being developed amid a debate over their utility compared to common fractions for merchants and tradesmen facing com
