I feel very pathetic for asking this but if you have to round 0.45 to the nearest whole number do you take the 5 into account as it would round the 4 to 5 and round to 1 or just base the rounding off the first decimal.

No. If you are rounding to the nearest whole number you round to 0 because 0 is .45 away from .45 and 1 is .55 away from .45.
