Answer 1

I will number your problems

1. ok
2. you need 6.5 ÷ 1/3 = 19.5
I would have expected a whole number, since it deals with people.
So 19 would receive a full 1/3 of a box, and the 20th person would get less than 1/3 of a box

3.
3^2 = 9 , which is rational
1/5 is rational
9^2 = 81 which is rational
.25 = 25/100 which is rational
all are rational

4. good
5. so at work she has (1/2)(2/3) = 1/3
6. good
7. ok, but I would write it as (-7)(-7)(-7)(-7)(-7)

Answer 2

5/6+ 2/3 you need to get the bottom number to the same number so x2 to the 3 making it 5/6 + 2/6 but I need to do what you did to the bottom to the tom so 2 x2= 4 so now we have 5/6 + 4/6 we add the top numbers 5+4= 9 9-6= 3 so sense 9 goes into 6 one time we have 1 9-6=3 so the answer is 1 1/2
