a. We know 760 mmHg = 1 atm then

555 mmHg = 555 mmHg * 1 atm / 760 mmHg = 0.73 atm

b. We know 1 psi = 0.068 atm  

Then 32.0 psi = 32.0 psi * 0.068 atm/1 psi = 2.176 atm

c. We know 760 torr = 1 atm

Then 675 torr = 1 atm * 675 torr / 760 torr = 0.888 atm

d. 75.2 mmHg = 75.2 mmHg * 1 atm / 760 mmHg = 0.09895 atm
