Is 0.33 the same as 1/3?

No, though it is close. 1/3 = 0.3, where the 3 repeats for ever, which never stops, and as a percentage it is 33 1/3%. 0.33 stops, so it is a little less than 1/3.

1/3 rounds to 0.33 at 2 decimal places. If a question says 1/3, work with 1/3 itself, not 0.33: 1/3 of 300 is exactly 100, but 0.33 of 300 is 99.
