---------
She must have 1/3 of it left.
----
(1/3)(3 1/2) = (1/3)[(2*3+1)/2] = (1/3)(7/2) = 7/6

If she uses 2/3 of it, she has +1+-+2%2F3+=+1%2F3+
of it left
-------------
3 1/2 yds = +%282%2F2%29%2A3+%2B+1%2F2+=+6%2F2+%2B+1%2F2+
+6%2F2+%2B+1%2F2+=+7%2F2+
----------------
She has 1/3 if this number of yds left, so
+%28+1%2F3+%29%2A%28+7%2F2+%29+=+7%2F6+ yds
------------------
+7%2F6+=+6%2F6+%2B+1%2F6+
+6%2F6+%2B+1%2F6+ = 1 1/6
She has 1 and 1/6 yds left
----------------------
check:
+7%2F6+%2B+%282%2F3%29%2A%28+7%2F2+%29+=+7%2F6+%2B+14%2F6+
+7%2F6+%2B+14%2F6+=+21%2F6+
+21%2F6+ = 3 3/6
3 3/6 = 3 1/2
OK
