Round 949 to the nearest ten and hundred pls

950- to the nearest ten

900- to the nearest hundred

Step-by-step explanation:

When rounding, the number that we look at is the number to the right of what we are rounding to.  When rounding to the nearest ten we look at the number to the right which is in the one's position.  In this case that is a 9.  In rounding, if the number we are looking at is 1-4 we round down an if the number we are looking at is 5-9 we round up.  Since the number is a 9 we round up and the nearest 10 above 49 is 50 so 949 rounded to the nearest 10 is 950.  We will repeat this same process when rounding to the hundred.  In this case the number to the right of the hundred is the ten which is a 4.  since it is between 1-4 we will round down.  the nearest hundred below 949 is 900 so 949 rounded to the nearest hundred is 900.

I hope this helps and please don't hesitate to ask if there is anything still unclear!
