Question 581769
Whoops, didn't see the link to the lesson. Yes, 2/5 = .4, not .2. I didn't write that lesson, so you can email the author of the website (who is also the owner of this website) if you wish, at ichudov@algebra.com. Make sure that you are clear with your notation; 2.2/5 is usually interpreted as 2.2 over 5 (or .44), while 2 2/5 means 2 and 2/5 (or 2.4), which is probably what you want.
