Answer :

Let's simplify the expression [tex]\(\frac{2 a b}{6 a}\)[/tex] step by step.

### Step 1: Factorize the terms
We begin by separating the constants, variables, and coefficients in both the numerator and the denominator.

- Numerator: [tex]\(2ab\)[/tex]
- Denominator: [tex]\(6a\)[/tex]

### Step 2: Cancel the common factors
In both the numerator and the denominator, we have the factor [tex]\(a\)[/tex].

[tex]\[ \frac{2ab}{6a} = \frac{2b}{6} \][/tex]

### Step 3: Simplify the fraction further
Now, we simplify the fraction [tex]\(\frac{2b}{6}\)[/tex] by dividing both the numerator and the denominator by their greatest common divisor (GCD).

The GCD of 2 and 6 is 2.

[tex]\[ \frac{2b}{6} = \frac{2b \div 2}{6 \div 2} = \frac{b}{3} \][/tex]

### Conclusion
The simplified form of the expression [tex]\(\frac{2ab}{6a}\)[/tex] is:

[tex]\[ \boxed{\frac{b}{3}} \][/tex]
