A question on 4th grade math course challenge asked for the conversion for 70/100 cm to millimeters. I typed in 700 mm (because millimeters is 1000 place values and centi only covers 100.) But it says my answer is wrong, and when I looked at the answer it said 70/100 cm was equal to 7 millimeters... I thought 70/100 cm was equal to 700 millimeters, yet it marked me wrong and now I can't pass with a 100% this round because of an error. Am I wrong or what?
