Answer :
You could easily do that yourself, with a pencil, and about the same amount of time it took you to post the question here.
If you go through and try them . . . 1/1, 1/2, 1/3, 1/4, 1/5 . . . etc., you'll find
that the thirds, sixths, sevenths, and ninths produce repeating decimals.
The oneths, tooths, fourths, fifths, eighths, and tenths don't.

The correct answer is:
3, 6, 7, 9
Explanation:
If your denominator was 1, you would have whole numbers, not repeating decimals.
If your denominator was 2, you would have halves. These do not repeat.
If your denominator was 4, you would have 0.25 or 0.75.
If your denominator was 5, you would have 0.2, 0.4, 0.6, or 0.8.
If your denominator was 8, you would have 0.125, 0.375, 0.625, or 0.875.
If your denominator was 10, you would have 0.1, 0.3, 0.7, or 0.9.
However, if your denominator is 3, you would have repeating 3's or 6's. If your denominator was 6, you would have a 1 with a repeating 6 or an 8 with repeating 3's. If your denominator was 7, you would have repeating 0.142857, repeating 0.285714, repeating 0.428571, repeating 0.571428, repeating 0.714285, or repeating 0.857142. If your denominator was 9, you would have repeating 1's, 2's, 4's, 5's, 7's, or 8's.
