"Round to the nearest percent if necessary." Do you know what that entails? A decimal is not a percent, but you can easily convert. Multiply $0.02$ by a 100%.

wonderwomen · Answer

but when you put it into a percent than it is  22%

wonderwomen · Answer

i mean .022%

anonymous · Answer

$0.02\not=0.02\%$
"Percent" means "parts per 100".

0.02 is equivalent to two hundredths, or 2 parts per 100, or 2%.
