On a climb up Mt. Whitney, the atmospheric pressure is 553 mm Hg.
if i want to find the atm....do i set up my problem like this 553 mm Hg X 1atm / 760 mm Hg or do i multiply 553 by 760 i get confused on which formula to use.

Just think of it like a fraction...
553 mm Hg = (533mm Hg)/1
Since mm Hg is on the top, it must cross cancel with the denominator.
(533mm Hg)/1 x 1atm / 760 mm Hg
So, the mm Hg cancel eachother out and you multiply the rest just like any fraction. You get...
(533 x 1 atm)/ (1 x 760mm Hg) = 530atm/760
Hope this Helps!
