When you round up to the nearest 100, you are finding the closest multiple of 100 that is greater than or equal to the given number. To round up to the nearest 100, you look at the digit in the hundreds place. If the digit in the tens or ones place is 5 or greater, you add 1 to the hundreds place and replace all other digits with zeros. For example, rounding up 345 to the nearest 100 would give you 400.

When rounding a number to the nearest 100, you have to take note of the digit in the 10 place. For example, if the number you are given is 2350 and you want to round it to the nearest 100, you would round it to 2400. If the number is 2345, however, you would round it down to 2300 because even though the 5 in the ones place would round the 4 in the tens place to a 5 if you were rounding by 10, you are not supposed to pay attention to numbers in the ones place when rounding by 100. Basically, you only pay attention to the number directly after the number you're rounding. Also, if you're rounding by 100 and the given number is something like 2970, you would have to round up to 3000.

How many 2 digit numbers can be rounded off to 100?

If you were told to round two digit numbers to the closest 100, you could round everything from 10-99 to the nearest 100, inclusive of 10 and 99. I.e all two-digit numbers round up to 100. This is because "to the nearest hundred" does not mean "up to 100, or down to zero", since "zero" is not in the "hundred's" catagory. i.e you can only round up to 100.This means you have 89 seperate two-digit number which will round up to 100.
