Better.

anonymous · Answer

Rational numbers: Terminating decimals like 5.5 or 5.3. Repeating decimals like 5.777777777777777.... or 3.5757575757........ An irrational number is a number that can't be written as a fraction, and it just keeps going on and on and on.

anonymous · Answer

Like pi, which has an infinite amount of numbers.

anonymous · Answer

Since 4/5 is already a fraction, that is a rational number, not irrational.

anonymous · Answer

3.8 is a terminating decimal, so do you think that would be irrational?
