When we round to the nearest hundred, the numbers “residing” in the red areas (up to 850) on the number line are rounded to 800. The numbers in the blue areas are rounded to 900.
Again, distance matters. Numbers from 801 to 849 are closer to 800 than to 900.
Numbers from 851 to 899 are closer to 900 than to 800. And the “middle guy,” 850, is rounded up to 900: 850 ≈ 900.
