Explanation:

Step1: Recall the conversion formula

The formula to convert Rankine (R) to Kelvin (K) is \( K=\frac{5}{9}\times R \).

Step2: Substitute the given value

We are given \( R = 540 \). Substitute this into the formula: \( K=\frac{5}{9}\times540 \).

Step3: Calculate the result

First, simplify \( \frac{540}{9}=60 \), then multiply by 5: \( 60\times5 = 300 \).

Answer:
