Answer 1

Good grief
You first posted this on Wednesday
and I replied you this way:

Then you reposted exactly the same way,
bobpursley gave you a reply assuming a typing error
http://www.jiskha.com/display.cgi?id=1360487406

Now you are posting it again, and behold, it again makes no sense
Did you mean 1/10 , 1/10 etc ????

If so just make the necessary changes in bob's solution.
