How many cases of measles would you predict were reported last year

In the laws of mathematics, especially in rounding off digits, you should take note of the digit following that number no matter how long or short a number is. If the numberis preceded by numbers between 0-4, the number does not change. However if its is preceded by numbers between 5-9, add one to the number. For example, 145698. If it is rounded off to the nearest hundreds, since 9 is the number after 6, add 1 to 6 and it becomes 145700. If it is rounded off to the nearest hundred thousands, since 4 is the number after 1, you do not add, the number stays the same and it becomes 100000
