It seems that you have mistakenly given the value. It is supposed to be 4.1% because 4.1 itself is already in decimal form. So how to write 4.1% into decimal form. Simply divide 4.1 by 100 and you get 0.041.So the decimal form of 4.1% is 0.041. Hope this is the answer that you are looking for. Thanks for posting your question.
