Question

Does leave as the whole percentage mean if it was 5.4% you would have it as 5%

Answer 1

It is about rounding.

You would round up or down depending on the number after decimal.

If it is < 5 you drop it, if equal or greater than 5 then round up to the next whole number.

5.4% is rounded down to 5% since 4 < 5.
