There were plenty of wars during this year. World War, Defensive War, and Winter War are just 3. You have to be more specific.

You are right that the second one is false. What state do you live in? I need to know that to know if it is the east coast.

Oh yes, Ms. Sue is right. I didn't even realize this as I did the steps. When going from 6 49/35, it doesn't become 6 14/35 because 49/35 is more than one..

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.

statistics
70+82+82+100+x/5=76 (There has to be at least two 82's since it is the mode.) Solve for x, and that's the third unknown.
