2 and 4/7 times 2 and 1/4 times 4 and 2/3 equals?

I'm not understanding how to do this equation. Can you explain how to solve it? I turned the mixed numbers into improper fractions, did some canceling, then multiplied, and the answer I got was 756/28, then I divided 756 into 28 and got 27? And you help me on how to multiply three fractions?
