Fiona can make 8 cards in 12 hour. She divides to find the number of cards she can make per hour, but she makes a mistake. Three of these reasons explain why her answer must be wrong. Which does NOT?

8 times one-half = 4. I can make 4 cards per hour.



The answer cannot be a whole number.


If she makes 4 cards in an hour, she cannot make 8 cards in just 12 hour.


4×12 does not equal 8.


There are more than 4 halves in 8 wholes.
