Pressure and volume are inversely proportional for a gas. If you increase the volume of a gas, then the pressure decreases.
Pressure x Volume = Constant
I'll go through an example question in this video:
A gas in a ball has a volume of 25 cm^3 and a pressure of 100000 Pa. The ball is squashed into a volume of 4 cm^3 without a change in temperature. What is the new pressure?
