I REALLY NEED HELP HERE!?

Question

I'm not asking you to do my homework for me, I just need some help on how to do this.

A sample of a certain lead compound contains 6.57 grams of lead for each gram of oxygen. A second sample has a mass of 60.89 g and contains 31.31 g of oxygen. Could the two samples be the same?

First answer that works gets 10 points!!

Answer 1

They can't be the same substance because the second substance would be comprised of mostly oxygen but the first substance would be comprised mostly of lead.  

Answer 2

Definitely NO

if you will put the first sample into a ratio

               1g (oxygen) : 6.57g (lead)

then the second sample:

               60.89g (total) - 31.31g (oxygen) = 29.58g (lead)

        

               (then put it into ratio)

               31.31g (oxygen) : 29.58g (lead)

               divide it into 31.31g (for the oxygen be equal to 1g)

                1g (oxygen) : 0.944g (lead)

Then:

1st sample:                                             2nd sample:

1g(oxygen) : 6.57g(lead)   is not equal to   1g(oxygen) : 0.944g(lead)

dont forget my stars ^^
