Write the expression 2a plus b in the form of a fraction with a denominator of b?

To express (2a + b) as a fraction with a denominator of (b), you can rewrite it as follows:

[ \frac{2a}{b} + \frac{b}{b} = \frac{2a + b}{b} ]

Thus, the expression (2a + b) in the form of a fraction with a denominator of (b) is (\frac{2a + b}{b}).
