You are adding air to a tire. The air pressure in the tire should be 24 27 200 pounds per square inch. What decimal should you w

vova2212 [387]

Answer:

P = 24.135 pounds per square inch

Step-by-step explanation:

The air pressure in the tire should be $24\dfrac{27}{200}$ pounds per square inch. This pressure is in the form of a mixed fraction. It is required to convert this pressure into a decimal form. We can convert it as follows :

$24\dfrac{27}{200}=\dfrac{(24\times 200)+27}{200}\\\\=24.135\ \text{pounds/square inch}$

In decimal form, the value of pressure in the tire on the digital pressure gauge is 24.135 pounds per square inch.
