Is there a way to tell if a decimal is terminating or repeating?
Think of the division problem as a fraction. Simplify the fraction to its simplest form. For example, simplify 7/14 to 1/2. If the only factors of the denominator are 1, 2, and 5, then it will terminate. If the denominator has any other factors, it will repeat. For example, n/16 will always terminate for any integer n. But n/15 will never terminate for any non-zero integer n if the fraction is in its simplest form. Another method is to do the division. If you are dividing a/b (where a and b are both integers), then if it is going to terminate, it will terminate within b-1 decimal places. In other words, the repeating portion will never be longer than b-1 digits.
What is 220 as a decimal?
