Example of error analysis response#1: The problem was completed incorrectly because the answer was 0.034. This showed that it is in the thousandths place. The fraction was 34/100. If I were to complete the problem, I would have place 34 over the two zeros. Then, the 1 would show the decimal. I would end up arriving at .34 .
#2: The problem was completed incorrectly because the solution was 0.034 and it should have been 0.34. One way to find the solution would be to say the fraction mathematically. You would say it as 34 hundredths. So then, we would write it as 0.34.
