Grade 9 - Rational and irrational numbers

Sorry about the confusion today.
Rational numbers are numbers that can be written as a fraction, they have terminating decimals (ones that end), or repeating decimals (whether it be a single number that repeats or a segment of repeating numbers).
ex. -2.85, 3.0, 0.123 123 123 123, 3/4

Irrational numbers: the decimals neither end or repeat. You cannot tell a pattern and cannot predict what number is coming next.
ex. Pi (3.141592654...., 0.12345634562347
