The first numeral after the decimal place is tenths. The second is hundredths, and the third is thousandths. 0.18 is already rounded up to the nearest thousandth; you can't round it up because there is no ten thousandths to round it up from. Sorry; this is a little confusing.
It's already in its thousandth place
300/621 = 0.48309. Round your answer to 1 decimal place. Your answer should be 48.3%. Hope this helps. God Bless!
