The average is just all of the amounts added together and then divided by 9 because that is how many days and data there were. I converted the numbers so they had the same denominator . So 2/10+3/10+4/10+1/10+1/10+3/10+2/10+2/10+2/10= 20/10=2 You then divide this by 9 2/9= 2/9 inches per day on average
