Answer 1

Hey mate,

Here is the solution :-

$\frac{a}{b} = \frac{3}{4} \: \: \: \: \: \: \: \: \: \: \frac{b}{c} = \frac{6}{5} \\ \\ \frac{a}{b} = \frac{3}{4} \times \frac{3}{3} = \frac{9}{12} \\ \\ \frac{b}{c} = \frac{6}{5} \times \frac{2}{2} = \frac{12}{10} \\ \\ a = 9 \\ b = 12 \\ c = 10 \\ \\ \frac{a}{c} = \frac{9}{10}$

I hope this will help you....
