Question

what is 13.2 round to the nearest whole number

Answer 1

13.2 first look at the 2 if is lower then the number five so u round down to 0 the decimal stays there so it's no 13.0 now u do the same to the 13 only u round up since its higher so u round it up to 20 and ur answer should be 20.0

Answer 2

when rounding off decimals to the nearest whole number you look for the number to the  right of the decimal point  if it is below 5 take the number that you have before the decimal eg. 13.21543 rounded to the nearest whole number would be 13 if it was 13.91234 the whole number would be   14 because 9 is higher than 5 use 5 as a gauge of what is high and what is low
