One can convert temperature from kelvin into fahrenheit using the formula f = 9/5 (k - 273) +32. what is the temperature in kelvin corresponding to f degrees fahrenheit?

You are being asked to solve for K given F.

Subtract 32 from both sides. Put brackets around the two terms on the left.

(F - 32) = 9/5(K - 273)       Multiply both sides by 5/9
5/9(F - 32) = K - 273         Now add 273 to both sides
5/9(F - 32) + 273 = K

You are actually converting the F temperature to Celcius first. Once in degrees C, you are then adding 273 to make it degrees Kelvin.
