Solve the Fraction Problem: 6/5 minus 2/5

Let's solve the problem by carefully following these steps:

• Step 1: Identify the numerators and the denominator
  The fractions are $\frac{6}{5}$ and $\frac{2}{5}$. Both fractions have a common denominator of 5, with numerators 6 and 2 respectively.
• Step 2: Subtract the numerators
  Since the denominators are the same, we can directly subtract the numerators: $6 - 2 = 4$.
• Step 3: Retain the common denominator
  The result of the subtraction will have the same denominator, which is 5. Therefore, the resulting fraction is $\frac{4}{5}$.

Thus, after performing the subtraction, we find that:

$\frac{6}{5} - \frac{2}{5} = \frac{4}{5}$

Therefore, the correct answer to the problem is $\frac{4}{5}$, which matches the provided choice with ID 4.
