This cannot be properly answered because you did not say what place to round it to. For example; nearest whole number, hundreds, tenths, etc.
4.05 rounded to the nearest whole number is 4
Rounded to a whole number it is 4
4 As the number after the decimal point is greater than 5 the number is rounded up
It is then 4 when rounded to the nearest whole number
It then would be 7 because .4 is less than .5
It rounds to 4 when rounded to the nearest whole number.
Anything from 3.5 to 4.4
The answer would be 5, because .5 rounded from one doesn't change from .5, then 4 rounded from .5 would cause the number to increase.
If rounding to a whole number, it would round to 4.
If rounded to a whole number, it would be rounded to 8.

It would be 3.7. Rounded to the nearest whole number is 4.
If a number is 1.2, it would be rounded to 1 because a half is 0.5. If the number is 1.25 it would be rounded to 1.5. If the number is 1.24 it would be rounded to 1.
