Would you round 14.47 to 14 or 15? ?

14

Step-by-step explanation:

When rounding to a whole number, you round down if the decimal in the 10th's place is below 5, you round up if the decimal is 5 or above.  

Ex:  12.4  rounds down to 12 because there is a 4 in the 10th's

       12.5 rounds up to 13 because there is a 5 in the 10th's place

        14.47 rounds down because there is a 4 in the 10th's place, the 7 in the hundredth's place would only affect the 4 in the 10th's place when rounding.  It wouldn't affect the 14.  

15

Step-by-step explanation:

If the first digit is 4 or under then you either leave it or round it down, if the digit is 5 or over then round up no matter what. If there is a digit in the hundreds place then the same rule applies as well, in this example you can round the .47 to a .5 which is 14.5 and since the digit is 5 we round it to 15.
