\]
Write your answer as a fraction in simplest form.

Step 1 ：Given the problem, we need to subtract the fractions \(\frac{5}{6}\) and \(\frac{3}{5}\).

Step 2 ：To subtract fractions, we need to have a common denominator. The common denominator of 6 and 5 is 30.

Step 3 ：So, we need to convert both fractions to have this common denominator. We get \(\frac{25}{30}\) and \(\frac{18}{30}\).

Step 4 ：Then, we can subtract the numerators. We get \(\frac{25}{30} - \frac{18}{30} = \frac{7}{30}\).

Step 5 ：After that, we simplify the fraction if possible. In this case, the fraction is already in its simplest form.

Step 6 ：Final Answer: The result of the subtraction is \(\boxed{\frac{7}{30}}\).
