Question 7 of 75

Which of the following is a rational number?

3.245
all of the other choices
3.245245…
3.24...
Explanation

All of the other choices. 3.245245... is periodic (AMBIGUOUS), 3.245 terminates, and 3.24... is periodic.(AMBIGUOUS) I thought periodic decimals need a bar over the repetend.
