I will give you the formula and try to pulg the value in and solve it your-self.  If you still need help e-mail me back.

Proportional means it eqauls so:

P=T

Now inversely proportional means that the number is getting divded;

So in this case the eqaution is 

P=T/V because V is inversly proportional to P, with temperature as being porportional.

So for B it's:

Rerrange the formula:

V=T/P

So:

V=400/33.2 --> solve that.



For c) it's P=500/80 --> solve that.
