1. The problem involves two fractions being added and then the third fraction multiplied by the result of that addition. 2. Let's denote the first two fractions as $\frac{a}{b}$ and $\frac{c}{d}$, and the third fraction as $\frac{e}{f}$. 3. The operation is: $$\left(\frac{a}{b} + \frac{c}{d}\right) \times \frac{e}{f}$$ 4. To add the first two fractions, find a common denominator: $$\frac{a}{b} + \frac{c}{d} = \frac{ad}{bd} + \frac{cb}{bd} = \frac{ad + cb}{bd}$$ 5. Now multiply this sum by the third fraction: $$\frac{ad + cb}{bd} \times \frac{e}{f} = \frac{(ad + cb) \times e}{bd \times f}$$ 6. This is the simplified expression for the problem. 7. If you have specific values for $a,b,c,d,e,f$, substitute them to get the numerical result.
