Question from Kenneth: Hello: It is correct to express 0.5% as 5 tenths of one percent. Is it also correct to express 0.5% as 5 tenths of one-hundred percentage points or 5 tenths of one percentage point? I think it would be 5 tenths of one percentage point because 5 tenths of one-hundred percentage points would be 50 percentage points, but I'm not sure. I thank you for your reply. |
Hi Kenneth,
You are correct that 0.5% is 5 tenths of one percent. Since 5 tenths or $\large \frac{5}{10} \mbox{is} \large \frac12,$ you can also express 0.5% as half of one percent.
