Math CentralQuandaries & Queries


Question from Emily:

How do you divide repeating decimals by whole numbers?

Hi Emily,

I have two suggestions. The first is to write the repeating decimal to at least 3 repeats and then use long division or your calculator to do the division. The result should be a repeating decimal.

The second suggestion is to write the repeating decimal as a rational number in fractional form. Here is an example, and another. Now yo have a fraction divided by a whole number. Write this in fractional form or as a decimal, which will be repeating.
