------------------------------------------------------------------------
y varies inversely with x. If y=1.6 when x=0.5 find x when y=3.2
------------------------------------------------------------------------

y=k%2Fx
-
1.6=k%2F0.5
k=0.8
-
highlight%28y=0.8%2Fx%29

Your question asks for x, when y is 3.2.
x%2F0.8=1%2Fy
x=0.8%2Fy
x=0.8%2F3.2
