To the nearest ten: 860

To the nearest hundred: 900

The lowest number that rounds to 700 to the nearest hundred would be 650.

Half of 100 is 50, so the smallest number that rounds to 400 to the the nearest hundred is 400 - 50 = 350.

1. We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

2. We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

3. If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
