Your answer is correct. Good job! 2 5/7 + 1 2/5 + 3 2/7 2 25/35+ 1 14/35 + 3 10/35 6 49/35= 6 14/35= 6 2/5

I did explain it, Mary. We already know that you have a 70 and 100. There has to be at least 82's since it's the mode (occurs the most). We can then solve for the missing number. (70+82+82+100+x)/5=76..x will be the last missing number.
