The old price is +5%2F3+ dollars/pound
The new price is +2%2F3+ dollars/pound
-----------------
The fraction of the decrease in price is
+%28%28+5%2F3+-+2%2F3+%29%29+%2F+%28%285%2F3%29%29+
+%28%28+3%2F3+%29%29+%2F+%28%28+5%2F3+%29%29+=+1%2F%28%285%2F3%29%29+
+1%2F%28%285%2F3%29%29+=+3%2F5+
------------------
The percent decrease in price is:
+%283%2F5%29%2A100+=+60+
60%
