Answer
a) $(38\frac{8}{9})^{\circ}$ $\approx$$(38.89)^{\circ}$ C
b) Temperature in K $\approx$ 312.0 K
Work Step by Step
a) Use relation connecting temperature in Celcius (C) and Fahrenheit,
C= $\frac{5}{9}$(F-32) to get the answer.
b)Use relation K= C+273.15 to obtain corresponding Kelvin temperature from Celcius temperature.
