Answer:
6 sub-pieces, each 1/3 of a full piece of toast
Explanation:
Divide "2 pieces of toast" by "1/3 piece of toast:" This results in:
2 pieces
------------- = 6 sub-pieces
1/3
Suppose you lay out the 2 pieces of toast. You then cut them up, one at a time, cutting each full pieces into 3 sub-pieces. Obviously you get 3 (1/3 pieces). Now repeat that with the other full piece; again, you get 3 (1/3) pieces, or a total of 6 from the original 2 full pieces.
