Question 635269: Pressure varies inversely as volume. When the pressure is 16 pascals, the volume is 84 liters. What would the volume be if the pressure is reduced to 12 pascals?
The equation I used is P = k/V (P stands for pressure, V for volume.)
Plug in the values and get 16 = k/84, which simplifies to k= 1344.
After that, you take P = k/V again and plug in P and k for this equation:
12 = 1344/V
I know that V is equal to 112 but how do you solve for V? Can you show me the steps?

very simple first you multiply the last equation completely by V and you get and then we just divide both sides by 12 and we get V=112
