19.83 x 1.07 = <span>21.218

To answer this question you need to divide to get the number of pieces and then multiply whats leff by 3 2/3.
Divide 3 2/3 by 2/3. There are a few ways to do this but I am going to turn 3 2/3 into an improper fraction and then divide.
So

Now divide


We can see she can get 5.5 pieces at 2/3. So .5 is going to be left over so we ask our self, what is .5 of 3 2/3? We times .5 by 3 2/3 = 1.83 yards left. If you want it into a fraction, it would be

yards left
423 divided by 898 is 0.47104677...
Hope I could help! :)
