Chad buys peanuts in 2pound bags. He repackages them into bags that hold 5/6 pound of peanuts. How many 2pound bags of peanuts should Chad buy so that he can fill the 5/6pound bags without having any peanuts left over?

6 small bags hold 5 pounds.
The nuts come in 2lb bags, so we need to bag up 10 lbs not to have any left over.
So, how many 2lb bags in 10 lbs? 
52 pound bags

1 4/6

Please be advise textbooks some times have mistakes wording problems. This problem read to me to pack 5/6 of a pound, not 5/6 of a 2pound bag, so the answer cannot be 3, 5 or 6 bags. It is 15 bags because he needs to repack bags with no peanuts left over.
1 pound = 6/6. Since he repacks into 5/6, there is 1/6 left for every pound.
Then for every 2pound bag he has 2/6 leftover.
2pound bag = 12/6  10/6 = 2/6
For every three 2pound bags he repacks into 5/6, he has 1/6 left over.
In five 2pound bags he gets 5/6 more, enough to make small bags with zero left over. Each two lines of 1/6 represents 2pound bag.
1/6 1/6 1/6 1/6 1/6 1/6
1/6 1/6 1/6 1/6 1/6 1/6
1/6 1/6 1/6 1/6 1/6 1/6
1/6 1/6 1/6 1/6 1/6 1/6
1/6 1/6 1/6 1/6 1/6 1/6
1/6 1/6 1/6 1/6 1/6 1/6
If you make this 5 times, you'll see the result. 15 bags of 2pound. 
I looked at marycruz's answer and I cam up with 30 because if marycruz said ",15 bags of 2pound ", then you have to multiply 15 x 2. And you get 30

(15×2=100)+30 100+30=130

3 bags

This is the correct answer.
5/6+5/6+5/6+5/6+5/6+5/6=30/6
= 5 Pound Bags. 
The correct answer is three 2 lb bags. For every 2 lb bag he buys he repackages in bags that hold 5/6. A 2 lb bag equals 12/6, which he repackages into two 5/6 bags which equals 10/6. 12/6  10/6 = 2/6 left. So for every 2 lb bag he buys, 2/6 is leftover. 2/6 + 2/6 + 2/6 = 6/6, therefore he would need to buy three 2 lb bags.

10/2

I think all of yall wrong because it asking for how many bags should he buy thise numbers are to high he might not have that much money the answer 6 because we learned this question in class

15
