Yes, if you are rounding to the nearest ten. No, if you are rounding to the nearest whole number.
0.45 should be rounded down to 0.

To round to the nearest whole number, you first take only the digits greater than the decimal part. In this case, we have 45. The next step is to look at the tenths place in the decimals, and if it is 5 or greater we must round up. In this case, it is 3, so we don't need to round up. Thus 45.37 rounded to the nearest whole number is 45.
If a number is already a whole number, and you are being asked to round it to the nearest whole number, then you don't need to round it anymore, since itself is the nearest whole number.

It IS a whole number!
45% is a fraction and there is no sensible way to express it as a whole number.
