What’s the ratio in simplest form if you count 14 robins out of 150 birds

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

‼️‼️‼️‼️‼️the pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is 440 f, find the pressure exerted when the temperature of the gas is 380°f. (show work)
