You can put this solution on YOUR website!
Let +x+ = pounds of water to be added
+.56%2A1+=+.56+ pounds of chlorine in 56% mix
-----------------
+.56+%2F+%28+x+%2B+1+%29+=+.12+
+.56+=+.12%2A%28+x+%2B+1+%29+
+.56+=+.12x+%2B+.12+
+.12x+=+.44+
+x+=+3.667+
3 and 2/3 pounds of water are needed
---------------
check:
+.56+%2F+%28+3.667+%2B+1+%29+=+.12+
+.56+%2F+4.667+=+.12+
+.56+=+.12%2A4.667+
+.56+=+.56+
OK
