List these from least to greaest 86% 47/50 0.89

86%, 0.89, 17/50

This is because 0.89 as a percentage is 89% (because when you convert a decimal to a fraction, you jump two decimals to the right, and if you're making a percentage into a decimal, you jump two spaces to the left) and 47/50 is 90%. So, obviously 90% is over 89%, and 89% is over 86%.
