Round 12.29 to the nearest whole number

12 because 2 is not bigger than 5 so the number stays the same. fir example if it was 12.87 the answer will be 13

To round to the nearest whole number you use the over five rule. Lets start with .09 see that 9 is over 5 and round the two in front of it up one to 3 so now you have 12.3 is what we have so far now since 3 is smaller than 5 we forget and leave it as 12 so the nearest whole number is 12 ^^
