There are 15 "A" particle and 5 "B" particles in one picture. These particles combine to form 5 compounds, each consisting of 3 "A" and 1 "B" particle.

Which equation below best describes the stoichiometry of this reaction?

A + 3B ----> AB3

5A + 15B ---> 5AB3

I know what stoichiometry means, but to best describe it, should I reduce to the smallest coefficients?  I really don't see that it makes a different.  I could really just use someone's opinion on this question.
Personally, I would go with the reduced formula.  What does everyone else think?

Any input would be of immense *delete me*  Thank you!

I don't see anything that has the 3A to 1B ratio?

OOpps.  My mistake.  I'll repost my question below.

look carefully at what u've written

yes a reduced formula would be better.
