To get the mass of the oxygen do the mass of the dish + lead oxide subtracted by mass of the dish + lead.

I got pb mass 3.132 and O as 0.322
then the mol of pb as 0.0151 and O as 0.020125
then Pb-1 and O 1.3 i think i did something wrong

That seems to be correct, I think all you have to do now is get the oxygen to a whole number. By x by 10, but I don't know, I feel like there' something weird.

Pb3O4 bc the o was 1.33
Ah yes, I orginially did that, but because it was not exactly 4 I had did something else.
look here it shows you how to do it, it may help!
