You can put this solution on YOUR website! If x varies directly as y, and x=12 when y=2, find x when y=10.
===============================================
Do it like this:
----
If z varies inversely as w, and z=30 when w=0.4, find z when w=10.
------------
z = k/w --- k is a constant
30 = k/0.4
k = 12
==================
find z when w=10.
z = 12/10
z = 1.2
