The elements x and y combine in different ratios to form four different types of compounds: xy, xy₂, xy₃, and xy₄. consider that there is enough of each sample to contain 2 g of x, and the mass of x is estimated to be 2 g and the mass of y is estimated to be 4 g.
arrange the following ratios in order of their increasing value. (the exercise gives me three tabs to put in order from highest to least. these are in the pic)

rank from highest to lowest ratio. to rank items as equivalent, overlap them.
i put xy₄ as highest, then xy₃ in the middle, and xy₂ as lowest. is this order correct? i'm not quite understanding this lesson : // so if i could also get some sort of an explanation, that'd be
