What decimal is greater 0.3 or 0.32?

0.32 is greater than 0.3. When determining which decimal is greater, first look at the first digit after the decimal point to see which is larger. If they're the same (like in this case) move to the second digit. If there is no digit (as in the case of 0.3), assume that it's zero. Since 2 is larger than 0, that makes 0.32 larger than 0.30.
