x the cost per pound
%282%2F3%29%2F1+=+.64%2Fx | Cross Multiplying to solve
(2/3)x = .64
x = (3/2).64 = .96 per lb
%283%2F2%29%28.96%29 = $1.44

----
cost/weight = cost/weight
-----
x/(3/2) = 0.64/(2/3)
----
x = (3/2)*0.64/(2/3)
----
x = (9/4)*0.64
x = 9*0.16
x = $1.44

If you got three times as much candy, you would have gotten:
+3%2A%28+2%2F3+%29+=+6%2F3+
+6%2F3+=+2+ pounds
That would have cost you 3 times as much, or:
+3%2A.64+=+1.92+
----------------
This is the cost for 2 pounds, so 1 pound costs:
+1.92%2F2+=+.96+
96 cents
And a half pound costs +.96%2F2+=+.48+
48 cents
So, 1 and 1/2 pounds costs:
+.96+%2B+.48+=+1.44+
$1.44
------------
Here's a rough calculator check:
+.64+%2F+.6667+=+1.44+%2F+1.5+
+.95995+=+.96+
close enough
