You inflate a front tires on your car to 22 psi. later, you measure your blood pressure, obtaining a reading of 127/61, the readingbeing in mm hg. in metric countries (which is to say, most of theworld), these pressures are customarily reported in kilopascals(kpa).
in kilopascals, what are (a) your tire pressure
kpa
(b) your blood pressure?
/ kpa

a) 1.5 × 10² kPa

b) 16.9/8.1

Explanation:

a) The pressure of the front tires is 22 psi. The appropriate conversion factor is 1 psi = 6.89 kPa. The pressure of the tires in kPa is:

22 psi × (6.89 kPa / 1 psi) = 1.5 × 10² kPa

b) Regarding the blood pressure, the minimun reading is 61 mmHg and the maximum reading is 127 mmHg. The appropriate conversion factor is 1 kPa = 7.50 mmHg. The blood pressure in kPa is:

61 mmHg × (1 kPa / 7.50 mmHg) = 8.1 kPa

127 mmHg × (1 kPa / 7.50 mmHg) = 16.9 kPa
