Answer:
Third step
Explanation:
To find the average amount it fell every hour, you need to divide -13 1/5 by 4 2/5. Since you can't do it with a mixed number, you need to make it an improper fraction by multiplying the denominator by the number and adding the numerator.
Now you divide the new numbers. However, in the problem, it is multiplying, so that is what's wrong.
Therefore the third step is wrong.
