I Need Some Help With Chemistry?

I was sick for 2 days and my teacher is easily distracted. Please help me! These questions don’t make any sense!
1. ____Pressure= force/surface area. For a constant force, when the surface area is tripled the pressure ___
a) is tripled
b) is reduced by 1/3
c) is unchanged
2. Rank the following pressures in increasing order:
(a) 50 kPa (b) 76 torr (c) 2 atm (d) 100N/m^2
If someone could also explain the conversions between atm, Pascals, torr and mmHg I would be eternally grateful!
