Find the quotient simplify if possible x/3 , x/9

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
