A bucket holds 4 quarts of popcorn. If 1/3 cup of corn kernels makes 2 quarts of popcorn, how many buckets can be filled with the popcorn made from 4 cups of kernels?

The answer is 6, but I can't see why it's 6. Please exlplain to me how the answer is 6. Thanks in advance...

Well, how many quarts of popcorn can 4 cups make if 1/3 cup makes 2? 4 is 12x bigger than 1/3, so 12 8 2 quarts = 24 quarts. 24 / 4 quarts = 6 buckets

GOD, how bad is your school?

Ok, 24 quarts of popcorn will be made because 1/3 cup makes 2 quarts.

Divide 4 by 1/3 and you should receive 12. Multiply 12 by 2 and you should receive 24. A bucket holds 4 quarts. Divide 24 by 4 and you should receive 6.

Here's an easy way to look at this problem:

1/3 cup makes 1/2 bucket of popcorn.

You have 4 cup and that's 12 1/2 buckets of popcorn.

Now, how many full buckets of popcorn do you have?

If 1/3 cup of corn makes 2 quarts of popcorn, 1 cup makes (3)(2)=6 quarts, and 4 cups would make (4)(6) = 24 quarts of popcorn. If a bucket holds 4 quarts, you would need (24/4) = 6 buckets to hold 24 quarts.

Take it easy Tri, not everyone's strong point is math.

But yeah, Im not gonna waste space because the posters above have sufficiently answered the question.

Hope you understand now.

I know this has been explained. But anyway:
If 1/3 cup makes 2 quarts, and the question is all about 4 cups, I ask myself "how many 1/3s are in 4?" Then I can use division and say that 12 1/3s are in 4. Now, 1/3 cups makes 2 quarts, so 12/3 cups make 2 x 12=24 quarts. Now I see that each bucket holds 4 quarts. So I can see that I would have to divide 24 by 4 to see how many buckets I would need, in this case:6.
