Question

12351 rounded to the nearest hundred explain how you rounded

Answer 1

12351 rounded to the nearest hundred = 12400

** 12351.....find the number in the hundreds position....it is the 3...now look to the number directly to the right of it....if that number is 5 or above, that 3 is rounded up to 4, but if that number is 4 or below, that 3 stays the same. So, the number to the right of 3 is 5, therefore, we round the 3 up to 4....making it 12400.

try this for practice...
12351 rounded to the nearest thousand.....find the number in the thousand place....it is a 2....now look to the number of the right of it....it is a 3....and since it is less then 5, that 2 stays the same...so ur answer would be 12000

just remember, if the number is 5 or above, it rounds up 1, but if the number is 4 or below, it stays the same.
