In the number 3,400 the greatest place would be the 3. And in 800, the greatest place would be the 8. Basically it is the highest value in a number.

Instead of rounding each number to a given place value, we round whatever number is in the front.

A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. So, a decimal number will always round to a decimal number.
Instead of rounding each number to a given place value, we round whatever number is in the front.
To round a number to a certain place value, you look at the digit immediately to the right of that place value. If it is 5 or greater, you round up; if it is less than 5, you round down. For example, to round 3.785 to the nearest hundredth, you would look at the digit in the thousandths place (8), which is 5 or greater, so you round up to 3.79.

Without being given to the nearest, I will assume you want the greatest number that could possibly be rounded in each case:320: to the nearest 320, any number greater than or equal to 320/2 = 160, and less than 320 + 320/2 = 480 will round to 320. Thus the greatest whole number that rounds to 320 is 479.220: to the nearest 220, any number greater than or equal to 110, and less than 330 will round to 220. Thus the greatest whole number that rounds to 220 is 329.If decimals are considered, there is no exact answer to the greatest number in each case other than by saying they are less than 480 and 330 respectively.eg the greatest number to round to 320: 479.9 is close, 479.9999 is closer, 479.99999999999 is closer still, but an extra digit 9 can always be appended on to the end of any (decimal) number specified to make a bigger number that also rounds to 320.
The answer depends on the degree to which the number needs to be rounded.
