$$\frac{1}{\frac{1}{2}} + \frac{2}{\frac{2}{3}} + \frac{3}{\frac{3}{4}}$$ $$=$$

= 2 + $$\frac{6}{2}$$ + $$\frac{12}{3}$$

= 2 + 3 + 4

= 9

$$\frac{1}{\frac{1}{2}} + \frac{2}{\frac{2}{3}} + \frac{3}{\frac{3}{4}}$$ ..

$$\frac{1}{\frac{1}{2}}=\frac{1*2}{1}=2 ...... \frac{2}{\frac{2}{3}}=\frac{2*3}{2}=3 ..... \frac{3}{\frac{3}{4}}=\frac{3*4}{3}=4$$.....

So, $$\frac{1}{\frac{1}{2}} + \frac{2}{\frac{2}{3}} + \frac{3}{\frac{3}{4}}$$ $$=2+3+4=9$$
