If the fraction reduces to 36 and its denominator is 6x5, then the numerator should be 36 times 6x5. Simplifying this expression gives us 216x5. Therefore, the correct answer is "d) 216x5".

To simplify the expression, we can divide 5.4 by 1.2 and multiply 10^12 by 10^(-3). This gives us:
5.4 / 1.2 = 4.5
10^12 × 10^(-3) = 10^(12 + (-3)) = 10^9
Therefore, the expression can be simplified to 4.5 × 10^9. Hence, the correct answer is "b) 4.5 × 10^9".
