Question

Please help. Don't understand this. :(

Answer 1

an example of a repeating decimal would be 6.78787878. a rational number is a number that can be represented a/b where a and b are integers and b isnt equal to 0, so any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number
