Answer 2

To simplify the expression $\frac{x}{ab} + \frac{x}{ac}$, you need to find a common denominator for the two fractions, which in this case is $abc$. Then, rewrite each fraction with the common denominator:

$$\frac{x}{ab} + \frac{x}{ac} = \frac{x \cdot c}{abc} + \frac{x \cdot b}{abc}$$

Now that both fractions have the same denominator, you can add them together:

$$\frac{x \cdot c}{abc} + \frac{x \cdot b}{abc} = \frac{x \cdot c + x \cdot b}{abc}$$

Finally, simplify the numerator:

$$\frac{x \cdot c + x \cdot b}{abc} = \frac{x \cdot (c + b)}{abc}$$

So, $\frac{x}{ab} + \frac{x}{ac} = \frac{x \cdot (c + b)}{abc}$.
