Answer 2

Answer:

0.15 is the correct answer.

Step-by-step explanation:

Solution:

$\implies \sf (4^{ - 1} - 5^{ - 1} ) \div 3^{ - 1}$

$\implies \sf ( \frac{1}{4} - 5^{ - 1} ) \div 3^{ - 1}$

$\implies \sf (\frac{1}{4} - \frac{1}{5} ) \div 3^{ - 1}$

$\implies \sf ( \frac{1}{4} - \frac{1}{5} ) \times {3}^{1}$

$\implies \sf \frac{1}{20} \times {3}^{1}$

$\implies \sf \frac{1}{20} \times 3$

$\implies \sf \frac{3}{20}$

$\implies \sf 0.15$

Hence, The correct answer is 0.15.
