Step-by-step explanation:

At constant temperature, volume and pressure are inversely related. Increasing the pressure by a factor of 125/50 = 2.5 will cause the volume to be reduced by that factor.

  volume = 5.0L / 2.5

  volume = 2.0 L

How do u work out 75% of 32 ??
vladimir1956 [14]

And 32 is the same as 32/1 because anything divided by one is itself
Now we use multiplication :
