3. how is a rational number converted to its decimal form?
4. why is division by zero not allowed?
5. how can you determine whether a rational number will have a terminating or a repeating decimal form?
6. how is a repeating decimal written?

4. division by zero is not allowed because zero has nothing to divide

3. It depends, is it is a fraction or already a decimal? With fractions, you just divide the numerator by denominator.

4. Nothing times 0 can get anything beyond 0.

5. Again, you just have to divide the numerator by denominator, assuming it's a fraction.

6. A repeating decimal is written with a little line over the parts that repeat.
