Substances A and B are colourless gases obtained by combining sulfur and oxygen. Substance A results from combining 6.00g of sulfur with 5.99g of oxygen, and Substance B results from combining 8.60g of sulfur with 12.88g of oxygen. Show that the mass ratios in the two substances are simple multiples of each other.

How would I get started on this question the part that confuses me is the mass ratio.  Any little Hints would be appreciated.

A mass ratio is a ratio that is constant no matter how much components it contains.
Example: mass of grapes=10g, mass of candy= 5g
      Each sample has 10 components: 10 grapes(10g/1grape)= 100g
                                                      10 candy(5g/1candy)= 50g
                                                             mass ratio= 100g/50g=2/1
      each sample has 20 components: 20 grapes(10g/1grape)= 200g
                                                      20 candy(5g/1candy)=100g
                                                             mass ratio= 200g/100g=2/1
