How do I place the decimal point in the product of two decimals?

Why are rational numbers terminating or repeating decimal?
Because terminating or repeating decimals can be written as the quotient of two integers a/b, where b is not equal to zero.
How fractions are related to repeating decimals and terminating decimals?
All rational fractions - one integer divided by a non-zero integer - give rise to repeating or terminating decimals. If, for the fraction in its simplest form, the denominator can be expressed as a product of powers of only 2 and 5 then the decimal will terminate. If the denominator has any prime factor other than 2 or 5 the decimal will be recurring. All non-rational fractions will have infinite, non-recurring decimal representations.
