What is PaO2/FiO2 when PaO2 = 95 mmHg and FiO2 = 0.30?

PaO2/FiO2 assesses how well the lungs transfer oxygen into the blood by comparing arterial oxygen tension to the fraction of inspired oxygen. You divide PaO2 by FiO2. Here, 95 mmHg divided by 0.30 equals 316.7, which rounds to about 317. So the value is roughly 317.
