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.
The smallest three digit composite number is 100, and the largest two digit number is 99. 100-99=1.
Both 10 and 20 are two-digit numbers that are factors of 20.
