**Example 1:** Round 0.1284 to 2 decimal places.

**Solution:** The 3rd decimal number, 8, is bigger than 4,
so we add 1 to the 2nd decimal number 2, and drop the rest of the
decimal numbers. Our answer is 0.13.

**Example 2:** Round 0.1284 to 1 decimal place.

**Solution:** The 2nd decimal number, 2, is less than 4,
so we do nothing to the 1 and drop the rest of the decimal numbers.
Our answer is 0.1.

**Example 3:** Round 0.895 to 2 decimal places.

**Solution:** The third decimal number, 5, is bigger than 4, so we
add 1 to 9 to get 10, and drop the rest of the decimal numbers. But, we
have to carry the 1 to the 8 to get 9. So our answer is 0.90 or just
0.9.
