To write a decimal into a percentage, you multiply it by 100. So, to write a percentage into a decimal, you would divide by 100. 24.1% ÷ 100 = 0.241. So, 24.1 as a decimal is 0.241. (Also, it could not be 241 or 2,410 because those are not decimals...and the question is asking for a decimal number)
