Describe how to round 678 to the nearest hundred.

The nearest hundred will be in the hundredth place

For example, 2000

2 is in the thousands, followed by hundreds, ten, ones

to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.

So in this case 678 will equal 700

Example: if it were 644, then it would be 600

hope this helps
